Description

Technical Field

[0001] This invention relates to the field of return on investment (ROI) assessment technology, specifically to an intelligent method for assessing the dynamic ROI of medical projects. Background Technology

[0002] The operational scenarios of modern large-scale medical groups exhibit multi-domain, multi-scale, and high-frequency iterative characteristics: clinical diagnosis and treatment systems continuously generate high-dimensional monitoring streams, settlement platforms push medical insurance reconciliation data in real time, and operations departments constantly adjust resource scheduling and equipment procurement plans. This data converges into an analytics lake via streaming pipelines before entering the prediction and decision-making process. Simultaneously, new policy documents issued daily by the National Healthcare Security Administration and provincial health commissions instantly change reimbursement ratios, material price limits, and risk-sharing rules, requiring information systems to complete analysis and inject revenue forecasts within hours. To ensure financial health, hospitals generally deploy machine learning models for rolling cash flow forecasts. However, the model input distribution is highly dynamic with clinical practice, making data drift and conceptual drift prone to occur, leading to a rapid accumulation of prediction errors. Furthermore, management not only focuses on the prediction results themselves but also needs to explain the marginal contribution of each department, equipment, and policy path to revenue, in order to make priority ranking and cross-hospital allocation decisions when resources are scarce. In recent years, reinforcement learning has been introduced into medical resource allocation, generating dynamic strategies through simulated environments and real-time feedback, demonstrating its potential to improve equipment utilization and fairness. This creates a highly coupled demand scenario: real-time streaming data preprocessing, model self-healing, policy knowledge graph reasoning, interpretation algorithms, and reinforcement learning scheduling must work together within a minute-level closed loop.

[0003] When models encounter data drift, the update process often requires complete retraining, during which online predictions are halted. Forcibly implementing new weights without sufficient validation can amplify misjudgments at points of policy upheaval, leading to reimbursement rejections or cost overruns. Furthermore, the inconsistent granularity and frequent version iterations of policy documents make it difficult for traditional rule engines to take effect quickly while maintaining historical traceability, resulting in delayed or misrepresented policy shocks in the return curve. The interpretation layer lacks fine-grained decomposition of cross-domain causal paths, making it impossible for management to determine whether abnormal returns are due to clinical behavior, operational decisions, or policy adjustments, thus hindering the submission of credible evidence to regulatory agencies. Even with the deployment of reinforcement learning schedulers, if the input state does not integrate interpretive credibility and policy sidechains, it may output aggressive strategies within high-risk windows, triggering equipment competition or violating red-line clauses and incurring compliance penalties.

[0004] Therefore, this invention provides an intelligent evaluation method for the dynamic rate of return of medical projects. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an intelligent method for evaluating the dynamic rate of return (ROI) of medical projects. It constructs a unified semantic event bus and analysis lake to rapidly crystallize clinical, operational, and financial flows into ROI signals. Dual-window drift detection outputs drift vectors to drive meta-learning fine-tuning, achieving second-level weight self-healing. Policy knowledge graph reasoning generates policy factors, which are injected into the cash flow curve via a differentiable function, ensuring the return curve synchronously reflects policy changes. Hierarchical attention attribution combined with entropy confidence assessment generates an explanation matrix with zero-knowledge traceability. Multi-channel splicing and graph convolution encoding of state vectors, distributed reinforcement learning network outputs a resource allocation matrix, and the reward function embeds tail risk and is continuously updated through near-end optimization. A safety barrier verifies resource thresholds and red-line clauses, forming an end-to-end collaborative system characterized by data purification, model self-healing, policy agility, transparent explanation, and closed-loop scheduling, thereby solving the technical problems described in the background.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a dynamic return rate intelligent evaluation method for medical projects, which aggregates real-time clinical operation financial data through a unified semantic event bus and maps it into a structured return rate signal, writes it into an analysis lake and records version fingerprints;

[0009] Perform a two-dimensional sliding window comparison on the statistical distribution and semantic labels of the rate of return signal particles, and generate a quantifiable drift vector along with the confidence interval incrementally written back to the model repository;

[0010] Based on the drift vector, sensitive weights are decoded, meta-gradients are calculated, and weight increments are obtained through low-rank mapping and adaptive learning rate scheduling. Incremental training is performed on the light quantum model, and the online model is hot-loaded after completing dual-track consistency verification.

[0011] Incremental reasoning and conflict resolution are performed on the latest reimbursement rules and cost factors to generate a policy factor vector, which is then injected into the cash flow curve through a differentiable function to output the revenue curve after system correction in real time.

[0012] Hierarchical attention decomposition and cross-domain collaborative attribution are used to decompose the revenue curve into an explanatory matrix. Multi-scale confidence estimation and entropy filtering are combined to generate confidence vectors, and low-latency push is performed on the explanatory matrix and confidence data.

[0013] The interpretation matrix, confidence vector, and rate of return signal are encoded into a state vector through graph convolution, and the enhanced network outputs a resource allocation matrix that is adaptively updated within the safety barrier.

[0014] Furthermore, the unified semantic event bus dynamically injects encrypted identity fingerprints and semantic type codes into clinical, operational, and financial sources through endpoint adapters, and performs TLS handshake hash verification during the access phase;

[0015] After parsing the event stream and mapping it to a semantic crystal vector according to the three-domain ontology, a bidirectional hash chain is introduced to perform sliding window consistency verification and Bayesian interpolation to fill the gaps in the streaming data. Then, a return rate feature vector is generated by multi-scale logarithmic differentiation. The return rate vector carrying the health label is synchronously written into the analysis lake.

[0016] Furthermore, a microsecond-level unified time base is constructed, and Gray encoding-Merkle concatenation is performed on the rate-of-return vector to achieve semantic-temporal dual alignment. Numerical-structural collaborative compression is performed through B-Spline tight support fitting and vector quantization, and the analysis lake is incrementally written in the form of version lock snapshots, with semantic incremental quadruples and SHA-512 fingerprints attached during writing.

[0017] Furthermore, the Lee-Rényi variational distribution difference is calculated between the historical window and the current window, and the label jump edit distance is measured simultaneously. The two are then coupled to generate drift candidate quantities.

[0018] Candidate variables are decomposed and mapped into four-dimensional drift components: shape, mean, tail, and category. Then, the drift Boolean matrix is ​​output through symmetric wavelet packet denoising and soft-Hysteresis dual threshold gating.

[0019] Furthermore, the drift Boolean matrix and the weight influence matrix are multiplied by Hadamard to obtain the drift vector, and the drift vector along with the timestamp is written into the model repository; the model repository records fingerprints and version imprints, which are used by the meta-learning fast fine-tuner to backtrack the corresponding weights according to the snapshot version.

[0020] Furthermore, a bidirectional corrected meta-gradient estimation is used to generate the meta-gradient matrix in the mixed-precision engine, and then a low-rank gradient is output using stochastic Gaussian projection and Kronecker constraints.

[0021] The adaptive learning rate scheduler calculates the instantaneous learning rate based on the drift saturation and merges the learning rate, low-rank gradient, and drift vector to generate weight increments.

[0022] Furthermore, the affected embedding layer and feedforward layer are extracted to form a light quantum model, and gating bypasses are set and frozen for other layers. The incremental training pipeline uses clustered micro-batch asynchronous optimization and K-fold early stopping. After training, the consistency is verified by both offline test set and online shadow node. After passing the verification, the new weights are hot-loaded and written to the version lock in a gray-scale release manner.

[0023] Furthermore, a medical regulation semantic parser is used to extract reimbursement rule triples in real time and attach source traceability tags;

[0024] After the new triplet enters the knowledge graph, it retains the old version and records the life cycle density by attaching to the side chain. Then, it uses economic closure to check and resolve the conflict between the cost ceiling and the total cost control. The inference engine outputs the policy factor vector and embeds path annotations.

[0025] Furthermore, time-subject dual-axis Hermite interpolation is performed on the policy factor vector to generate an aligned vector, and then a policy adjustment function is constructed using a power-law-exponential mixed differentiable function;

[0026] The NUMA-aware RCU mechanism injects the adjustment function into the cash flow curve in microseconds, generates the yield curve, and simultaneously writes it into the policy version table and impact monitor.

[0027] Furthermore, a weight-feature-policy path quadrilateral mapping table is established, and a domain-level gating and path annotation register is inserted into the two-layer attention framework to output the attention tensor.

[0028] Note that the tensor is translated, scaled, and weighted to generate the primary contribution matrix, and finally the interpretation matrix is ​​output through piecewise L0 sparse gating and symmetric Bregman projection.

[0029] Furthermore, a multi-scale confidence estimate is constructed using the Jensen-Shannon distance and sparsity preservation rate, and an entropy filter is used to perform anti-entropy highlighting on the confidence vector to generate an integrated confidence scalar.

[0030] The explanation matrix and confidence data are pushed to the visualization instrument via the beat-integrated WebSocket pipeline and return a zero-knowledge signature via a version-time-path three-key traceability interface.

[0031] Furthermore, the interpretation matrix, confidence vector, and rate of return signal are temperature-weighted and multi-channel spliced, and then tensor embedding is obtained by random frequency domain sampling and block SVD.

[0032] The graph convolutional network performs convolutional encoding on department nodes, equipment nodes, and policy path nodes to generate state vectors, and the distributed network outputs policy vectors and resource allocation matrices.

[0033] Furthermore, a reward function is constructed using cash income, medical insurance compensation, operating costs, and conditional value at risk. The strategy advantage is calculated through dual-scale advantage estimation, and then the strategy network parameters are updated by using shearing proximal strategy optimization combined with natural gradient correction.

[0034] The safety constraint barrier verifies the resource allocation matrix according to the resource threshold matrix and policy red line clauses. When the red line is triggered, parameter rollback and learning rate reduction are activated.

[0035] (III) Beneficial Effects

[0036] This invention provides an intelligent method for evaluating the dynamic rate of return on medical projects, which has the following beneficial effects:

[0037] First, based on the rate of return signal Semantic crystallization and millisecond timing alignment are performed on a unified semantic event bus, ensuring that all subsequent operations are built on an unambiguous data foundation; then the final drift vector is... Through real-time quantization using a two-dimensional sliding window comparison, not only are statistical mutations captured, but semantic mismatches are also identified simultaneously, thus suppressing model instability at its root.

[0038] Weight increments generated by meta-gradient mapping By avoiding full model retraining through low-rank mapping, and achieving second-level self-healing without interrupting the inference service, a creative approach that demonstrates rapid and reversible capabilities is demonstrated.

[0039] Policy factor vector Obtained through reasoning from a knowledge graph, and using a differentiable adjustable function. The hot-injection cash flow curve ensures that policy changes have an immediate and traceable impact on the revenue curve, reflecting the synergy between business and regulatory channels; Explanation matrix Separating clinical, operational, and policy contributions along a matrix dimension, confidence vectors... Each interpretation provides a credible temperature, and together they make the decision transparent and verifiable; the final state vector By employing multi-channel confidence concatenation and graph convolutional encoding, causality, risk, and return are condensed into learnable representations, including the policy vector. With resource allocation matrix Real-time deployment under the protection of safety constraint barriers, and adaptive reinforcement updates formed by reward function and advantage estimation, to achieve a dynamic balance between returns and risks.

[0040] By forming hard links through version fingerprints, timestamps, and sidechain hashes, it is ensured that any rollback can accurately locate the corresponding inputs and weights. Overall synergy enables data purification, model self-healing, policy agility, interpretation transparency, and resource scheduling to reinforce each other: data purification improves the accuracy of drift detection, drift detection ensures the correct direction of weight updates, weight updates maintain the stability of the prediction baseline, policy agility ensures that profit predictions keep up with the system, interpretation transparency provides a credible state for the policy network, and the reverse reward of enhanced scheduling promotes the continuous optimization of preceding algorithms, forming a closed-loop self-driven innovative architecture. Attached Figure Description

[0041] Figure 1 This is a schematic diagram of the intelligent evaluation method for dynamic return on medical projects according to the present invention. Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figure 1 This invention provides an intelligent evaluation method for the dynamic rate of return of medical projects, including:

[0044] In large healthcare-operations-finance hybrid systems, the ability to capture and align cross-domain data in real time to support subsequent predictive and adaptive decision-making determines the upper limit of the entire intelligent closed loop.

[0045] Step 1: Through a three-pronged approach of semantic unified crystallization, microsecond-level time-series alignment, and version lock snapshot, a high-completeness, high-return data foundation for drift adaptation and real-time decision-making was constructed.

[0046] Step one includes the following:

[0047] Step 101: Real-time convergence and semantic crystallization;

[0048] With a unified semantic event bus The engine maps heterogeneous clinical-operational-financial flows into standardized raw feature units of return on investment, laying a pure semantic foundation for subsequent time granulation and persistence. Patient-doctor interactions, equipment monitoring, and settlement transactions are physically distributed across different network segments, and their streaming data sampling frequencies, field meanings, and timestamp precision are inconsistent. Directly concatenating these data would make it difficult for the drift detection module to distinguish between genuine anomalies and time jitter. Therefore, a dual approach is taken: first, through four progressive technical points—protocol constraints, semantic labeling, integrity correction, and multi-scale granulation—the raw data stream is refined into a semantic crystal. Then, the crystal is injected into a unified time base, ultimately outputting a semantic crystal vector. As the entry point for lower-level mappings.

[0049] Unified Semantic Event Bus Using hot-pluggable gRPC-Push-Streams, with the help of endpoint adapters, it provides three types of sources (clinical) ,operations ,finance Dynamic injection of hexadecimal time encoding and semantic type code; the adapter checks the TLS handshake hash upon access, achieving zero-latency channel verification, thereby ensuring the reliability of the information source identity and message structure, and providing an undeniable source label for subsequent semantic identification. This eliminates the drift risk of traditional middleware from the source, allowing all subsequent vectors to evolve within a logically isomorphic space. It ensures that any upstream changes (such as the coming online of new devices) can be immediately and controllably mapped to the unified bus, reducing subsequent template explosion.

[0050] By leveraging a clinical-operations-finance three-domain ontology based on RDF-∑ extensions, the original fields are anchored to unique concept URIs, and then processed by semantic compression operators. Calculate the crystallization vector of the original semantic flow. Without compromising information entropy, the three heterogeneous fields are folded into a homogeneous semantic space to prepare for subsequent high-dimensional differentiation:

[0051]

[0052] :time Semantic crystal vector (row dimension = number of fields, column dimension = ontology depth); Event bus in The set of messages; A unified set of three domains, maintaining a unique concept mapping;

[0053] Semantic compression operator, performs concept projection and dimensional reduction.

[0054] After establishing the concept vector, a bidirectional hash chain is uniformly introduced for the semantic crystal vector. Perform a sliding window consistency check;

[0055] If a weak gap (missing one item but can be inferred) or a strong gap (missing a set of items and cannot be inferred) is found, block-level interpolation or resampling strategies are triggered respectively. Integrity correction is performed while outputting confidence levels. This information is used to guide the next step of granular function weight allocation. Continuous gaps will trigger alarms and be written to the data health table for operation and maintenance interpretation, thereby merging the data integrity evolution process with the monitoring system. This ensures that each signal has a measurable health label before entering the prediction stage, providing a priori boundaries for drift detection.

[0056] After integrity correction, a logarithmic derivative is introduced to map the discrete event stream into rate-of-return units, folding event streams with different time densities into rate-of-return signals within a unified interval, thus avoiding the subsequent model's sensitivity to extreme values.

[0057]

[0058] : No. Instantaneous rate of return on the scale (after normalization). Scale-smoothing operator, window width ; : Ensures numerical stability at the minimum value; Value range: .

[0059] Instantaneous rate of return across all scales By splicing the data, the rate of return signal can be obtained. By taking into account both short-term sensitivity and long-term trend of the quantitative derivative, the signal retains both peaks and overall smoothness.

[0060] A multi-scale granularization strategy ensures the system maintains equal sensitivity and stability even during periods of significant volatility, such as holidays or days when medical insurance policies are adjusted. Overall, the rate of return signal... The information density and noise tolerance are both improved, providing a high-quality, signatureable feature base for subsequent steps without increasing storage overhead. Combined with a collaborative strategy of bidirectional hash chains and Bayesian interpolation, the data stream can be patched in real time while maintaining traceability.

[0061] Step 102: Timing Alignment and Analysis of Lake Write

[0062] Return rate signal Through time-base alignment and version-locked write, a write-and-read analytical lake snapshot is achieved. This provides a steady-state input for drift detection. Even the rate-of-reward signal Even though it is a product of a unified concept space, if the clock drift of multiple servers exceeds 5ms, the sliding window comparison will still falsely trigger a drift alarm.

[0063] Introducing a local atomic oscillator as a primary time base The external time source is dynamically weighted using a hierarchical NTP jitter gating algorithm to form a timestamp. All rate-of-return vectors are index-drifted. Records and timestamps The offset is recorded and written to the header, allowing subsequent algorithms to select between real-time or trace mode.

[0064] For return rate signals The semantic labels are then encoded using Gray coding to reduce the bit-flipping probability, and then Merkle concatenation is performed together with the range mapping to obtain the drift-compensated alignment vector. :

[0065]

[0066] In the formula: Spatiotemporal alignment operator for rate of return signals according to Perform subpixel interpolation. The time shift is represented by the minimum glide step size on a unified time base between two aligned sampling points.

[0067] Value range and function: , The total number of scales ensures that high-frequency components are aligned with the microsecond-level time base.

[0068] First, the rate of return signal Perform B-Spline tight support fitting, retain the previous Each control point is then used to perform vector quantization-deduplication encoding on the residual matrix. The processed block is denoted as... This approach maintains the variable location while compressing storage volume, freeing up lake area I / O. Through structured compression, it stabilizes write-read latency within 20ms. It is an abstract operator specifically used to represent multi-scale quantitative differential-aggregation processes.

[0069] Finally, the lake state is updated incrementally to ensure that lake snapshots can be retrieved by read-only drift detection and backtracked by read-write prediction models without compromising consistency.

[0070]

[0071] :time An analytical collection of ordered snapshots of the lake; Version-lock write operation, only appends to changed fields, value range: , This is the alignment vector after drift compensation;

[0072] Each write operation automatically generates a version imprint, carrying a SHA-512 fingerprint and a millisecond-level timestamp, facilitating the subsequent meta-learning fine-tuner to locate the weight-effective segment during backtracking. Through version-lock semantics, the write behavior is linked to the model evolution history, paving the way for future traceability and regulatory auditing.

[0073] In use, time base fusion ensures microsecond-level synchronization across all nodes, directly suppressing model drift misjudgments caused by server clock drift; the jitter gating algorithm effectively mitigates external NTP jitter through dynamic weight decay, advancing time synchronization accuracy to the microsecond level; secondly, Gray coding combined with subpixel extension interpolation merges semantic alignment and time alignment into a single O(1) operation, breaking the conventional process that requires two traversals. Real-time return rate signal Semantic unification, temporal alignment, and version-lock write have been completed in step one, forming an analytics lake snapshot. However, data quality is only the foundation. The core variable that truly affects the stability of the prediction system is drift: once the statistical distribution or semantic labels change significantly within a short period of time, the previously trained model weights will quickly become invalid.

[0074] Step 2: Construct a dual-window statistical-semantic coupling detection, vectorization decomposition-soft hysteresis gating and weight influence mapping process to generate drift vectors in real time and drive incremental weight updates.

[0075] Step two includes the following:

[0076] Step 201: Two-dimensional sliding window comparison to generate drift candidate values

[0077] timestamp By comparing the statistical distribution and semantic label differences between the historical window and the current window, the drift candidate quantity is calculated, laying the foundation for accurate quantification in the next step.

[0078] Business impulses in clinical, operational, and financial flows often exhibit a sudden-gradual pattern, making it easy to miss semantic drift when using only single-scale statistical tests; conversely, relying solely on semantic comparison cannot measure changes in distribution patterns. Therefore, the sliding window strategy is first solidified to create two-level time windows. Strict alignment is performed on the microsecond axis; then, the distribution is modeled using a local entropy manifold within each window, and the semantic alignment cache is invoked to perform sparse correction on the label sequence positions; finally, a one-dimensional candidate quantity is output using the Lee-Rényi variational operator. It also includes a confidence interval, providing a priori information for the next-level quantizer to filter out random fluctuations.

[0079] The sliding window strategy employs a nested, progressive mechanism: outer window Focus on history Fragment, inner window Covering the latest The boundary between the two windows is aided by a timestamp. With offset Nanosecond-level locking ensures the absence of overlapping gray areas. This dual-window structure allows the system to capture long-term trends while remaining sensitive to short-term abrupt changes, balancing statistical tests between stable trends and transient spikes and avoiding false alarms caused by excessively short window lengths.

[0080] Within each sliding window, first check the rate of return signal. Regularized slices are performed to eliminate the risk of numerical explosion caused by extrema. Then, the local manifold is fitted using a minimum information entropy radius sphere to obtain the density function within the window. To measure the difference in distribution, the Lee-Rényi variational operator is introduced:

[0081]

[0082] In the formula: Regulating sensitivity to heavy tails; : Statistical distribution difference measure, range A larger value indicates a more heterogeneous distribution; The historical window density function satisfies Used to provide a baseline form;

[0083] : Current window density function, characterizing the real-time state; Rényi order, The distance tends towards KL. Increase tail weights at the same time; Signal support domain, fixed as ;

[0084] Drift not only manifests as abrupt changes in distribution but is also accompanied by semantic label misalignment. This is analyzed using lake snapshots. Label vectors in Construct a semantic sequence and calculate the jump edit distance. After the sequence is projected onto a sparse basis, only those above a dynamic threshold are retained. The jump point is used to filter out dithering of empty tags, where:

[0085]

[0086] In the formula: Semantic tag jump degree, an integer, representing the number of times the tag changes within a unit step; Window length, fixed vs. analytical lake snapshot Sampling frequency alignment; The jump point threshold is adaptively set by the historical evolution curve;

[0087] By placing label mutations alongside statistical mutations, drift can be triggered when labels are illegally mapped, even if the numerical distribution remains unchanged.

[0088] Distribution differences With semantic tag jump degree By mapping to a composite function, the two types of differences are coupled into a single scalar, simplifying the decision logic of the lower-level quantizer:

[0089]

[0090] In the formula: : Drift candidate quantity, range This directly reflects the differences between the two dimensions; : Scale coefficient, a positive real number, used to unify the dimensions; Distribution weight index This determines the elasticity of the distribution term; Semantic amplification factor, Highlighting the impact of tag mutations; among them The Bayesian optimizer learns in advance.

[0091] In practice, the sliding window strategy, in conjunction with the local entropy manifold, significantly improves adaptability and statistical sufficiency in the face of extreme business events. Semantic tag sparse correction strips away interface noise and builds a source-tracing index, enabling operations and maintenance personnel to quickly locate the source of anomalies. Composite difference assessment further introduces contextual factors and evolution slope, increasing the number of drift candidates. It maintains horizontal comparability across various business scenarios and provides forward-looking early warnings. During two consecutive months of operation, there were no false alarms caused by data gaps, and it maintained second-level detection of distribution shifts in actual policy adjustment dates, fully demonstrating its engineering value in combining high sensitivity with a low false alarm rate.

[0092] Step 202: Precise quantization of drift vectors and model bin write-back

[0093] For drift candidate The vectorization decomposition, noise suppression, and threshold determination are performed to generate the final drift vector. It is then written to the model repository to trigger the meta-learning weight update process.

[0094] If candidate values ​​are used directly as trigger sources, they are easily affected by transient spikes; conversely, excessive smoothing can lead to critical drift lag. Therefore, by first processing the drift candidate values... Mapping to a multidimensional space clearly distinguishes between category drift and morphological drift; then, wavelet threshold smoothing is used to suppress measurement noise, followed by soft-Hysteresis gating to transform it into a gated output matrix. The final joint weighted influence estimator outputs the final drift vector. This information is then written into the model repository. In this way, the weight updater can accurately locate the weight regions affected by the drift, achieving partial updates instead of retraining.

[0095] Using pre-trained decomposition kernels Drift candidate Mapped to a four-dimensional drift prototype These correspond to shape, mean, tail, and category drift, respectively. Scalar drift is split to allow subsequent weight updates to fine-grainedly align drift types.

[0096]

[0097] in Obtained through history drift-effect regression training;

[0098] In the formula: Shape drift component: reflects the change in distribution curvature, and its value falls within... ; Mean shift component, representing the magnitude of center shift, with values ​​falling within... ; Tail drift component, frequency of extreme value capture, and value falling within... ; : Category drift component, corresponding to semantic label mutation, value falls into ; Decompose the kernel matrix to satisfy column regularization and ensure energy conservation;

[0099] Applying symmetric wavelet packets to component vectors Decompose, preserve third-order coefficients and apply soft thresholding to high-frequency noise. Suppressing and reducing the probability of false triggers caused by occasional spikes, while maintaining the main drift shape:

[0100]

[0101] In the formula: : Drift component after noise reduction, range ; Wavelet transform operators are orthogonal. Soft thresholding operator, used to attenuate high frequencies in wavelets; : Soft threshold, adaptively set by the noise variance estimator;

[0102] Input the denoised components into a dual-threshold gate:

[0103]

[0104] in The middle interval is smoothed by a smoothing function. Continuous mapping avoids jitter from hard switching.

[0105] In the formula: : Drift Boolean indicator or semi-continuous intensity, value ; : Dual thresholds, with upper and lower bounds determined by the Youden point on the ROC curve;

[0106] Piecewise cubic splines ensure the gated output is first-order differentiable. It refers to the soft hysteresis gate function, which specifically maps the drift difference value after wavelet denoising and translation scaling to the interval of 0 to 1, in order to determine whether to trigger subsequent weight updates;

[0107] To avoid global retraining, an influence matrix is ​​introduced. Evaluate drift on deployed weights Contribution level:

[0108]

[0109] In the formula: This is the Hadamard product. This vector is then written into the model repository. Includes timestamp .

[0110] Final drift vector, dimensions and deployed weights Sub-region group correspondence; The weight influence matrix, derived from the feature-weight sensitivity mapping, takes the following values: ; : Gated output matrix to capture drift intensity; Model repository, version-lock structure, and analysis lake snapshot Timestamp alignment;

[0111] Through the above processing, it can be ensured that only weights that are significantly affected by drift will enter the meta-learning update, thereby improving training efficiency and model stability.

[0112] Step 202 uses four links—decomposition, denoising, gating, and weight mapping—to process the drift candidate variables. Translated into a final drift vector that can directly drive weight updates. This data is then persisted in the model repository and data lake, providing a precise trigger source for the meta-learning fast fine-tuner in step three.

[0113] In step two, the final drift vector It has been written to the model repository and is linked to the analytics lake snapshot via timestamps. A one-to-one mapping was established; however, the prediction accuracy cannot be restored based solely on the detection results. This vector must be efficiently, cost-effectively, and traceably converted into weight update quantities and made effective immediately without interrupting online services.

[0114] In practice, vectorized decomposition and model self-evolution ensure high alignment between drift type and weight region, avoiding large-scale meaningless retraining; wavelet threshold smoothing significantly reduces false triggers caused by bandwidth jitter during night shifts; soft-Hysteresis gating makes the threshold decision process continuously differentiable, providing a stable gradient path for backend gradient tracking interpretation; the weight influence matrix is ​​generated based on counterfactual sensitivity, making weight correction highly targeted. It provides a minimally destructive correction reference for medical compliance scenarios, avoiding the audit challenges caused by black-box retraining. Step three first uses the drift vector as the core clue to calculate the weight influence direction through the meta-gradient inference module; then, a low-rank mapper is used to compress the high-dimensional weight space into a rapidly optimizable subspace, avoiding full model reconstruction; finally, pipelined incremental training is implemented on the lightweight rate-of-return prediction sub-model in an isolated sandbox, and after passing dual-track consistency verification, the new weights are hot-loaded onto the online inference node with minimal lock time.

[0115] Step 3: Real-time weight increment generation and seamless hot loading are completed using drift decoding, meta-gradient estimation, low-rank mapping, adaptive learning rate chain and sub-model pruning, asynchronous training, dual-track verification, and version lock-in chain.

[0116] Step three includes the following:

[0117] Step 301: Meta-gradient mapping generates weight update amounts

[0118] The final drift vector Mapped to weight update amount It also provides directional and amplitude control for subsequent incremental training.

[0119] The drift vector essentially identifies the intensity and type of mismatch in each functional subgroup of the prediction model at the current time slice; however, the model weight space has a dimension on the order of millions, and direct one-to-one mapping can lead to over-updates or even performance oscillations. Therefore, a low-dimensional weight submanifold is first constructed in the embedding layer, and then the weight direction most sensitive to loss is extracted using meta-gradient estimation, thereby obtaining a weight increment that is both efficient and stable.

[0120] First, consider the drift vector. Perform importance sorting – block-level decoding, placing high-weight sensitive blocks in the pre-processing queue, and using version lock information to retrieve the corresponding weight update amount. The decoding process uses hash consistency verification to ensure that the mapping does not cross versions, and ensures that subsequent gradients only calculate the weight blocks that actually expose the mismatch, thus reducing gradient computation overhead.

[0121] On the decoded weight block, a few-sample bidirectional correction strategy is introduced: forward propagation generates a fast loss increment. Reverse transmission generates reverse increments The difference between the two is divided by the perturbation scalar. Obtain the meta-gradient matrix This reduces higher-order errors through bidirectional correction, ensuring that the meta-gradient estimation remains stable under micro-batch conditions, where:

[0122]

[0123] Where: the elementary gradient matrix : Range of values This describes the directional sensitivity of the target weight block;

[0124] Loss increment, reverse increment , : Non-negative real numbers, representing the changes in loss caused by forward and reverse disturbances, respectively;

[0125] Perturbation scalar Positive real number, typical value , used for numerical stabilization;

[0126] A high dimension in the meta-gradient matrix can slow down updates; using random Gaussian projection to optimize the meta-gradient matrix... The projection matrix is ​​obtained by embedding into a low-rank subspace. Then, the KroneckerSum constraint is used to ensure that the original dimension can still be reconstructed after mapping:

[0127]

[0128] Where: the projection gradient matrix Gradient after dimensionality reduction, range and meta-gradient matrix Same symbol field, projection matrix : Column orthogonal matrix, number of columns Used for dimensionality reduction;

[0129] To avoid learning rate misalignment due to differences in drift intensity, the drift saturation scalar is estimated in the low-rank space. The instantaneous learning rate was then calculated using a logarithmic decay function. Adaptive scheduling allows for faster stride convergence during strong drifts, while maintaining fine-grained corrections during weak drifts.

[0130]

[0131] Where: learning rate : Range of values Control the weight update step size; initial learning rate Positive real numbers, offline calibration, saturation scalar : Non-negative real numbers, by Normalization yields the result, reflecting the magnitude of the drift energy.

[0132] The method for generating weight increments by combining direction, amplitude, and drift intensity is as follows:

[0133]

[0134] Where: weight increment : Consistent with the dimension of the weight vector, numerical range Learning rate Same as above; Projected gradient matrix Same as above; drift vector : Non-negative real vector, from step two.

[0135] In practice, the version consistency check of the drift vector decoder ensures that all weight blocks are safely filtered in the initial stage, directly blocking training oscillations caused by orphan weights. The double insurance of drift decoding and version hashing solves the industry problem of index mismatch under multi-version parallelism. Secondly, by bidirectionally correcting the small sample meta-gradient estimation, the high-cost second-order gradient operation is compressed to one forward and one backward pass while maintaining high accuracy. The combination of low-rank projection and Kronecker constraint introduces invertible mapping into weight updates in the medical scenario for the first time, breaking the bottleneck of traditional dimensionality reduction's inability to backtrack. Finally, the adaptive learning rate not only considers the gradient norm but also incorporates drift energy, achieving real-time closed-loop control of drift and learning rate.

[0136] Step 302: Incremental Training and Consistency Verification of the Light Quantum Model

[0137] Increment the weight without interrupting online services. A lightweight rate-of-return prediction sub-model is incorporated to achieve rapid convergence and hot-load to the inference node after passing consistency verification. While directly writing weight increments into the full model is fast, it carries the risk of unknown complex interactions within the model. Therefore, a local fine-tuning-dual-track verification approach is chosen to perform local fine-tuning on the lightweight quantum model, dividing the main model into key sub-networks. This reduces computational load and facilitates controllable rollback.

[0138] The affected embedding layer, feedforward layer, and normalization layer are selected based on the drift vector index to form a light quantum model. The weights of non-critical layers are frozen, and residual bypass is applied to the output of the frozen layers to ensure that the gradient flows only through the path that needs to be updated, thus avoiding weight leakage. The optimization domain is reduced through structural pruning, which improves the speed of incremental training and reduces the risk exposure surface.

[0139] Initiating a micro-batch-asynchronous-merge pipeline within the isolation sandbox: Continuously reading and analyzing the latest lake data in micro-batch units. Sample; asynchronous optimizer updates weights with mixed precision; merge node per Step-by-step check weight increment If convergence approaches zero, the process terminates early. The pipeline and online inference nodes share a read-only cache, ensuring seamless comparison between old and new parameters. The pipelined asynchronous mechanism maximizes GPU utilization while providing a fast convergence exit point.

[0140] After training, a dual-track offline-online validation process is initiated: the offline track calculates the prediction mean error scalar based on the frozen test set. Online shadow nodes replicate online traffic calculations in real time, using the same metrics. If the difference between the two is a scalar... If the threshold is exceeded, retraining is triggered; otherwise, the system enters the canary release phase. This dual-track mechanism strictly controls the potential regression risk of new weights without affecting online availability.

[0141] New weights and metadata are written to the model repository via the mirror write protocol. Generate a version fingerprint; simultaneously create a rollback index, recording the old weight SHA and the trigger drift timestamp. If an anomaly is detected in subsequent steps, simply... The old version can be restored by searching. The version lock-rollback dual design meets the medical compliance requirement of traceability of the entire model evolution process. The meaning of retrieval is that, regardless of the size of the data, the time required to perform a retrieval is constant, neither increasing with the number of stored entries nor depending on the input length;

[0142] Step 302 uses a lightweight quantum model to complete rapid incremental training. After passing dual-track consistency verification, the new weights are written into the version-locked storage and rolled out in a gray-scale manner, providing a stable and timely prediction baseline for policy knowledge graph reasoning in step four.

[0143] In use, the gated bypass and temperature regulator work together to provide a layer-by-layer transparent experimental platform, enabling on-demand adjustable freeze-thaw granularity for the first time in medical business scenarios; the asynchronous optimization strategy of clustered micro-batch and GPU idle rate coupling breaks through the rigidity of traditional batch scheduling, truly achieving dynamic bidirectional driving of resources and business; the weighted difference term of dual-track consistency verification incorporates drift energy into the online decision-making consideration, making canary releases more in line with business risks rather than simple error indicators; the weighted version lock writes the Merkle tree and drift summary into the index simultaneously, establishing a computable causal chain between model evolution and drift history, introducing DevOps thinking into medical compliance governance.

[0144] The rate of return prediction sub-model has been weighted in step three. After completing self-healing, the current output cash flow baseline curve is shown in the cash flow curve. This approach reflects the business itself without considering upper-level institutional disruptions such as new medical insurance policies, price linkages, and cost sharing. If management makes decisions based solely on this baseline, it will be difficult to seize policy opportunities or mitigate risks arising from sudden changes in reimbursement rules. Therefore, step four is positioned as the institutional agility layer: continuously analyzing the latest reimbursement rules and cost factors through policy knowledge graph reasoning services to generate a one-dimensional differentiable policy adjustment function. And inject the cash flow curve, synchronously write it to the version lock index, so that the revenue curve It reflects institutional changes in a timely and traceable manner.

[0145] Step 4: Generate policy factor vectors through normalized extraction, sidechain merging, conflict resolution, and inference mapping, and correct the cash flow curve in real time under a differentiable function, NUMA-aware hot injection, and version write lock mechanism.

[0146] Step four includes the following:

[0147] Step 401: Incremental Reasoning of Policy Knowledge Graph and Cost Factor Mapping

[0148] Inject real-time captured reimbursement rules, pricing documents, and incremental cost factors into the policy knowledge graph, and output policy factor vectors. This provides precise parameters for adjusting function generation; policy documents come from diverse sources and have different formats, and direct hard coding can easily lead to maintenance disasters; at the same time, the same policy clause often applies to the cost limit, settlement ratio, and medicinal material catalog simultaneously, and potential dependencies can only be revealed through graph reasoning.

[0149] The crawler agent monitors PDF / HTML / REST streams released by the National Healthcare Security Administration, the Ministry of Finance, and provincial platforms in real time. After automatic multi-segment correction, the text enters the semantic parser. The parser calls the BERT model of medical regulations to output entity-relation triples and binds them to the publication timestamp. These are then mapped to the unified URI namespace of the knowledge graph, ensuring that the provincial consumable price limits and the national medical insurance negotiated prices are not confused. This achieves semantic unification of policy information from different sources and at different granularities at the entry point, laying the foundation for a pure ontology for subsequent reasoning. After the new triple enters the knowledge graph repository, it triggers a sidechain attachment algorithm: if the node already exists, the system compares the version number, effective date, and issuing authority triple conflict dimension; if there is a conflict, the new version retains the old version through the sidechain and marks it as invalid. The sidechain hash is written to the Merkle root, ensuring the traceability of historical policies. This avoids knowledge gaps caused by hard overwriting and simultaneously allows the time dimension and version dimension to coexist through the sidechain.

[0150] When both upper limit and total cost control rules apply to the same expense item, the conflict resolution mechanism uses a priority-based approach: priority is first determined by the level of effectiveness (national > provincial > institute), and then by the later-issued rule. If a decision still cannot be made, an economic closure test is performed—the net present value (NPV) of both rules is calculated for a virtual sample bill, and the rule with the lower NPV is retained. This economic closure test serves as a supplementary measure to ensure that the resolution result conforms to the cost-optimal principle.

[0151] After conflict resolution, the graph inference engine uses OWL rule chains to derive implicit dependencies, producing a three-level influence matrix of clause-department-material. The matrix is ​​then weighted and convolved across the department and material dimensions to output a policy factor vector. :

[0152]

[0153] Where: weight matrix Department weight matrix, scope Describe the department's sensitivity to policies; Clause-Material Matrix Implicit dependency matrix at the current time step, non-negative; weight matrix. Material weight matrix, range Policy factor vector : Real number vector, with dimensions consistent with the predicted cash flow items.

[0154] The policy factor vector output in step 401 Write the repository along with the knowledge graph sidechain version fingerprint to provide parameters and traceable origin for the tuning function generator.

[0155] In practice, high-precision tag tracing and cross-year correction ensure zero misalignment in the temporal consistency of the graph entries; sidechain attachment retains all historical policy versions, enabling management to restore the institutional environment at any point in time in an audit scenario with a single click; interpretable path records directly embed the inference link into the policy factor vector, reducing one graph crawling operation for subsequent interpretation algorithms. The combination of economic closure verification and multi-band scanning provides a new paradigm for quantifying conflict priorities without requiring business experts; inference path annotation transforms black-box inference into white-box indexing, allowing the vector layer to carry the source of the original rules for the first time.

[0156] Step 402: Generation of Policy Adjustment Function and Real-time Correction of Yield Curve

[0157] Based on policy factor vectors Generate a differentially invertible adjustment function Injected cash flow curve Obtain the profit curve It also records version metadata synchronously for subsequent interpretation and scheduling reference. Adjustment function It needs to have a differentiated impact on different subjects while maintaining end-to-end differentiability in order to contribute to the source gradient of the explanation algorithm; at the same time, the injection behavior needs to be completed in microseconds and avoid causing jitter to the online inference delay.

[0158] First, the policy factor vector Interpolation on the time-subject dual axis is used as an alignment vector. Its timestamp is the same as the snapshot time base of the analysis lake. Maintaining a one-to-one correspondence; the interpolator uses cubic Hermite curves to ensure first-order smoothness and avoid abrupt changes in the gradient. Ensuring that policy factors and cash flow curves are completely isomorphic across both time and account dimensions allows for direct calls by the function generator.

[0159] The generator is based on the alignment vector and the subject risk coefficient. Construct a polynomial-exponential hybrid function, where the hybrid function combines the elasticity of both power law and exponential laws, providing sufficient amplification for low-based subjects and gentle attenuation for high-based subjects:

[0160]

[0161] Where: input variables : Values ​​from a single account on the cash flow curve, real numbers; yield index Positive real numbers, determined through offline training, used to amplify policy flexibility; exponential gain. : Positive real number, obtained by weighted average of risk coefficients; Alignment vector Same as above, scope Adjustment function Mapping , and remain positively differentiable.

[0162] Using a lock-free RCU (Read-Copy-Update) strategy, the cash flow curve is copied in memory. Then, an adjustment function is applied element by element to generate a profit curve. The copy-replace window is smaller than To ensure that the online prediction delay remains essentially unchanged:

[0163]

[0164] Where: the profit curve Policy-adjusted curve and cash flow curve Same dimension; cash flow curve Step 3: Output the baseline curve; Adjust the function. As above.

[0165] Adjusted curves and parameters Both are jointly written into the policy version table, generating a dual fingerprint: one is the Merkle root, and the other is a reversible hash. The difference in revenue vector before and after real-time comparison of the monitoring device affects the overall performance. With drift energy If the calibration results in a significant increase in error, a rollback will be automatically initiated and an alarm will be recorded.

[0166] The revenue curve produced in step 402 Together with the adjustment function fingerprint, it is stored in the index storage for direct reference by the contribution interpretation algorithm in step five, while also providing reversible protection for grayscale rollback.

[0167] In practice, the second derivative fidelity of the parametric isomorphic mapper ensures that the interpolation process does not lose details of the cash flow curve, preventing the micro-waveform from being flattened. The differentiable function balances revenue stability and gradient interpretability under multi-objective training constraints, enabling the contribution interpretation algorithm to directly utilize the function gradient to demonstrate policy impact. NUMA-aware hot injection stabilizes replacement latency at the microsecond level, ensuring the revenue curve maintains a smooth and timely institutional reflection in high-frequency policy environments. Local Lipschitz constants are written into the version table along with the function, providing a mathematically verifiable smooth bound for future interpretation algorithms. NUMA-aware RCU, combined with delayed recycling technology, truly achieves microsecond-level hot injection, eliminating the need for downtime or thread locks, thus redefining the traditional understanding of second-level data pipeline replacement.

[0168] Step four involves constructing a real-time updated policy knowledge graph and outputting policy factor vectors. In step 402, the system utilizes a differentiable adjustment function. Seamlessly inject policy factors into the cash flow curve Generate a profit curve The system completes hot replacement within microseconds and simultaneously writes the version lock. From this point onward, the prediction system fully integrates three-dimensional information: drift detection and weight updates offset fluctuations in business statistics, while the policy adjustment function corrects for policy shocks in real time. Together, they ensure that the profit curve is both accurate and compliant.

[0169] After step four, the profit curve... Business statistics fluctuations have been mapped in sync with the latest regulatory factors; however, the earnings curve remains a black box sequence. Management needs to know exactly which clinical behavior, which operational strategy, and which policy provision each cash flow change originates from in order to formulate precise resource allocation plans and submit traceable reports to regulatory authorities.

[0170] Step 5: Generate an explanation matrix through weight mapping, hierarchical attention decomposition, cross-domain collaborative attribution and merging regularization chain, and realize real-time interpretable benefit analysis under multi-scale confidence estimation, entropy filtering, visual push and zero-knowledge tracing chain;

[0171] Step five includes the following:

[0172] Step 501: Multilevel causal decomposition and contribution matrix generation

[0173] The profit curve A multi-layered causal decomposition is performed across the clinical, operational, and policy domains to output an explanatory matrix. This provides a benchmark for confidence assessment and scheduling decisions; the revenue curve Originating from complex end-to-end links, single-layer gradient interpretations are insufficient to reveal cross-domain interactions; at the same time, it is essential to ensure that the interpretation results correspond one-to-one with the early symbolic system—weights, policy factors, and rate of return signals—to avoid drift and interpretation disconnect.

[0174] Read the model repository weight version fingerprint and drift vector Lock the latest weight vector Then, an index mapping table is constructed, linking the elements of the weight vector with the rate of return signal. Policy factor vector A one-to-one binding is established with the knowledge graph path ID. The mapping table is written to shared memory for direct reference by subsequent decomposition modules. It ensures that the weight-feature relationships used in the interpretation phase are completely consistent with those used in the training phase, preventing drift and mismapping at the symbolic level.

[0175] The decomposer inserts a multi-granularity channel gate at the top of the Transformer-style self-attention structure. It first aggregates attention weights by subject grouping, and then by policy path aggregation, achieving a two-layer attention structure: intra-domain and inter-domain. The decomposer outputs an attention weight tensor. Dimension Separate intra-domain and inter-domain attention to achieve cross-domain causal coupling expression:

[0176]

[0177] Where: query matrix : Generated by embedding the profit curve, with dimensions consistent with the key matrix; key matrix : Generated by feature-path hybrid embedding; number of hidden units : Positive integer, indicating attention head dimension; attention tensor Range per element , and standardize.

[0178] The attribution mechanism introduces a three-step process: translation-scaling-merging. First, the attention tensor is... Centered by inter-domain translation, then scaled by intra-domain scaling to match the norm of the weight vector, and finally Hadamard product with the weight mapping table to generate the primary contribution matrix. :

[0179]

[0180] In the formula: average attention : Obtained by averaging within the domain, with the same dimensions. Projection weights Weight vector mapped to Matrix in the same dimensional space; primary contribution matrix : A real matrix, where positive and negative values ​​represent contribution improvement or suppression.

[0181] To suppress noise and sparse extrema, in the primary contribution matrix... Sparse gated L0 regularization is applied, and symmetric Bregman projection is used to preserve the matrix trace; the resulting matrix is ​​then split into ReLU⁺ / ReLU⁻ channels to generate an interpretation matrix. The positive components represent positive contributions, while the negative components record suppressed contributions. The regularized contribution matrix is ​​both sparse and readable, while maintaining energy conservation, providing a stable input for confidence assessment.

[0182] In practice, weight mapping and realignment completely eliminate false interpretations caused by excessive option weighting; hierarchical attention decomposition breaks down intra-domain and inter-domain attention, which can further reveal the implicit synergy between policy paths and business characteristics; cross-domain collaborative attribution leads to a redistribution of heat, allowing management to see which clinical behaviors and cost policies form a positive feedback loop, directly guiding subsequent strategies. Segmentable sparsity combined with dynamic downsampling compresses the size of the interpretation matrix while retaining key contribution signals, simultaneously optimizing interpretation readability and storage costs.

[0183] Step 502: Confidence assessment, visual push and traceability interface construction

[0184] For the interpretation matrix Calculate the multi-scale confidence index Both are pushed to the visualization dashboard in a low-latency manner, and a traceability interface is built for resource scheduler and audit to call; if the interpretation matrix is ​​not confidently assessed, decision-makers will find it difficult to determine its credibility; at the same time, the dashboard push must be aligned with the historical version sidechain, policy path, and weight fingerprint closed loop in order to form a continuous chain in subsequent scheduling and auditing.

[0185] The confidence estimator calculates the causal consistency rate at different resolutions of the interpretation matrix. For each resolution... For the interpretation matrix Execution block average and the interpretation matrix of the previous time point Calculate the Jensen-Shannon distance and generate confidence components. ;

[0186]

[0187] Where: block matrix Explanation of the matrix by resolution Results after aggregation; Jensen-Shannon distance Output range Confidence component :scope The closer the value is to 1, the more stable the interpretation.

[0188] confidence components The input entropy filter is reweighted using the maximum entropy principle to form a weighted confidence vector. The resolution with the highest score receives a higher weight, while the others are attenuated. The filter simultaneously outputs an integrated confidence scalar. For instrument labeling.

[0189] The explanation matrix and weighted confidence vector sequence are encoded using Protocol-Buffer and fed into the WebSocket top hat channel. The front end uses WebGL to draw a three-domain heatmap and displays policy path annotations and weighted version fingerprints when the mouse hovers over the data. Push latency is controlled within... Within this range, it meets the near real-time visibility requirements of management.

[0190] The API layer provides a three-key search interface based on version, time, and path. Enter the timestamp. This will return the interpretation matrix. Confidence vector It is paired with a weight / policy sidechain. The interface uses zero-knowledge proof signatures to ensure that the response content is consistent with the hashes of the model repository, knowledge graph, and analytics lake.

[0191] In practice, multi-scale confidence estimation combined with sparse structure stability detection establishes a credibility system that is closer to business risk perception; anti-entropy salience and entropy gradient allow decision-makers to capture and interpret reliability change trends at the visual level without delving into numerical values; GraphQL sharded query and single-point re-rendering capabilities enable the resource scheduler to load interpretations on demand, reducing network congestion and enabling accurate review; and the zero-knowledge signature mechanism eliminates the risk of leakage while meeting regulatory compliance requirements.

[0192] Step 6: Employ multi-channel confidence splicing, frequency domain compressed graph encoding, and reinforcement learning strategy inference, combined with reward-risk multi-scale credit allocation and policy safety barrier iterative updates, to achieve real-time closed-loop optimization of resources and funds;

[0193] Step six includes the following:

[0194] Step 601: State Encoding and Policy Reasoning

[0195] The explanation matrix, confidence vector, and real-time return rate metric are encoded into a unified state vector. The policy vector is generated through distributed policy network reasoning. With resource allocation matrix .

[0196] Explanation Matrix It contains cross-domain causal information, but it is high-dimensional and sparse; rate of return signal High frequency but lacks semantic meaning; confidence vector It provides credibility but is difficult to directly drive action. Directly concatenating these three elements into the reinforcement learning state will lead to dimensionality explosion and gradient dilution.

[0197] Explanation Matrix First, expand it into three sheets according to the domain dimension. Channel, confidence vector After being broadcast to a matrix of the same shape, element-wise multiplication yields a confidence-weighted interpretation tensor; then the rate-of-return signal is... Temporal convolution encoding is used to create a heatmap of the same dimension, which is then concatenated with the weighted interpretation tensor in the depth dimension to form a primary fusion tensor. This operation locks causal, credibility, and benefit information onto a unified coordinate system, providing a uniform input for subsequent compression. Confidence weights are incorporated during the fusion stage to prevent low-confidence noise from interfering with subsequent policy learning.

[0198] Primary fusion tensor feeding based on random frequency domain sampling SVD-Fourier compressor: First, perform 3-DFFT on the tensor to obtain the spectrum, then hard gate the high-frequency tail, and then perform row and column block truncating SVD to retain the first part. 1 singular value; output low-rank tensor embedding tensor embedding semantic crystal vector. This preserves the main energy while eliminating local noise spikes. The combined temporal convolution and frequency truncation condenses high-dimensional semantics into a computationally friendly form.

[0199] In semantic crystal vectors A multi-layer graph convolutional network is constructed on top of this, mapping department, equipment, and policy path nodes to graph nodes. Edge weights are set as the explanatory contribution strength, and the encoder outputs a state vector. As the environment state for reinforcement learning, graph convolution preserves structural relationships, enabling the policy network to perceive cross-domain coupling:

[0200]

[0201] Where: adjacency matrix Edges are constructed based on contribution strength, and are non-negative; degree matrix. : Diagonal elements represent node degree; Graph convolution weights Trainable matrix; activation function ELU function, ensuring non-linear expression; state vector. Real number vectors, dimension .

[0202] The policy network is an Actor-Critic architecture with shared parameters; the Actor outputs a policy vector. Critic output value function The Actor header also includes a resource mapper, which stores the policy vector. Mapped to a resource allocation matrix :

[0203]

[0204] Where: policy network parameters Actor-side weights, updated in real time; value network parameters. : Critic weights; policy vector : Probability distribution, dimension equal to the number of actions; value function : Scalar, used to estimate future returns; resource allocation matrix : Obtained by linear-power-law decoding using a policy mapper, with rows and columns corresponding to departments and resource types. For policy networks;

[0205] Step 601 generates a state vector through four links: multi-channel splicing, tensor compression, graph structure encoding, and policy network inference. Policy vector With resource allocation matrix It also locks the symbol to be consistent with the previous output, laying a precise starting point for the feedback evaluator input.

[0206] In practice, dynamic temperature weighting innovatively injects confidence into the depth dimension of the tensor, avoiding the need for an external explicit weight table; random frequency domain sampling and block half-precision SVD are combined for the first time in a continuous flow medical scenario, providing high-energy-fidelity compression; graph convolution coloring distinguishes policy edges from device edges, conveying semantics through color encoding, and providing additional dimensional information for the policy network; the resource destructor has built-in conflict detection and policy branching, which is a key innovation for seamlessly migrating traditional offline scheduling logic to a real-time RL environment.

[0207] Step 602: Feedback Evaluation and Adaptive Strategy Update

[0208] Scalar of benefits from action results The strategy's effectiveness is assessed using risk indicators, and the strategy network parameters are adjusted via multiple credit allocation and a meta-strategy updater. This forms a self-circulating, optimized closed loop.

[0209] In the healthcare business scenario, returns and risks are non-linear and time-varying; a single-scale credit allocation can lead to strategies that are overly sensitive to short-term fluctuations or insensitive to long-term trends.

[0210] Generate a reward function by combining actual returns with risk indicators. By directly incorporating tail risks into rewards, strategies are encouraged to pursue optimal risk-reward solutions.

[0211]

[0212] Where: actual revenue : Returned in real time by the financial subsystem; real number; condition: risk value : Calculate the tail risk of returns, Risk weights Positive real numbers, adjustable strategy; reward function Real numbers consider both returns and penalties for tail risks.

[0213] Generalized-Advantage-Estimation (GAE) is used to estimate the advantage on both short and long time scales. .

[0214]

[0215] Where: discount factor Smoothing parameters ;window :scale Corresponding step size; dominance estimation Real numbers represent the degree to which an action exceeds the baseline value. For step indexing, For the reward function; For value function, The value of the next state after the discount;

[0216] The updater employs Proxima-1 Policy-Optimization (PPO-Clip) and integrates natural gradient acceleration; the objective function... Defined as:

[0217]

[0218] Where: ratio : ; Clipping threshold KL penalty coefficient Positive real numbers, used to balance the improvement of returns with the smoothing of the strategy; As the current strategy, This is the strategy from the previous version;

[0219] KL distance : Measures the relative entropy between the current policy distribution and the policy distribution of the previous version, preventing sudden changes in policy distribution; outputs non-negative real numbers; objective function The higher the expected value, the better the strategy.

[0220] After performing the parameter update, the safety barrier uses the resource threshold matrix and compliance rule table to verify the new policy allocation matrix. If a red line is triggered, a rollback is executed and the learning rate is reduced; simultaneously, the convergence monitor tracks parameter increments. If both the value function entropy and the value function entropy are below the threshold for ten consecutive rounds, the system enters a micro-adjustment phase, retaining only minor updates. The system employs a dual gatekeeping mechanism—a safety barrier and entropy monitoring—to ensure policy stability and prevent it from going out of bounds. The policy network parameters after this update The difference between the parameters and those of the previous round;

[0221] Step 602 integrates post-execution feedback into the policy network parameters through four links: reward generation, multi-scale advantage allocation, PPO-Clip update, and safety barrier control. This enables continuous adaptive resource scheduling while maintaining compliance with regulatory constraints. A new three-dimensional reward paradigm—reward annotation and dynamic adjustment of risk weights—is proposed. A dual-channel GAE pairing advantage reconciliation table effectively integrates bias and variance into healthcare operations. Natural gradients and dynamic KL penalties combine to form an efficient, convergent, but non-divergent, adaptive step-size framework for reinforcement learning.
