Description

Technical Field

[0001] The present invention relates to the field of talent training technology, and specifically to an artificial intelligence-based customized talent training system for big health. Background Art

[0002] Currently, talent training in the healthcare sector generally adopts a standard curriculum system that cannot adapt to individual physiological characteristics and dynamic industry needs. Traditional solutions rely on manual experience to design training content and lack continuous tracking of users' real-time biological indicators and psychological states, resulting in a rigid training path. The existing system is single in data collection dimensions, unable to integrate multimodal information, and unable to support personalized capability modeling. In addition, virtual training scenarios are disconnected from real health management tasks, the feedback mechanism lags, and training strategies cannot be dynamically optimized. To address the above problems, there is an urgent need to build a customized talent training system based on artificial intelligence, which can achieve closed-loop control from data collection to path optimization through multi-source data fusion and adaptive algorithms.

[0003] Traditional technologies rely on fixed training plans, ignoring the changing physiological state and abilities of users. Existing systems only analyze biological indicators or behavioral data, failing to dynamically adjust training paths by integrating multiple sources of information. Training content is often manually preset, resulting in a slow response to individual differences and failing to meet users' actual needs for personalized and customized training.

[0004] Existing technologies are insufficiently capable of simulating health management scenarios. Virtual training often relies on static models, which provide no real-time feedback on training effectiveness and optimization suggestions. Model updates lack adaptive mechanisms, and the feedback process is simplistic. Due to the lack of multi-objective balancing and closed-loop control, existing solutions struggle to dynamically correct deviations, easily becoming stuck in fixed patterns and unable to respond promptly to environmental changes, impacting overall training effectiveness.

[0142] The multimodal data collection module overcomes the limitations of traditional single-dimensional data collection by integrating four types of data: biological indicators, behavioral logs, psychological assessments, and industry requirements. Biosensors capture physiological signals such as heart rate and blood pressure in real time, behavioral logs record users' daily health management activities, psychological assessment scales quantify emotional states, and industry requirements data dynamically updates job skill requirements. The collection of multi-source, heterogeneous data provides high-density, multi-perspective user portraits for subsequent analysis, avoiding training biases caused by one-sided data.

[0143] The data processing and knowledge fusion module addresses the time misalignment issue of multi-device data. The dynamic time warping algorithm aligns cross-device time series data, eliminating interference caused by differences in device sampling frequencies. A conditional generative adversarial network fills in missing values, generating synthetic data consistent with the user's true physiological state and addressing data sparsity. Complete, aligned, and structured data provides reliable input for personalized modeling, avoiding model distortion caused by data fragmentation in traditional solutions.

[0144] The personalized capability modeling module uses a multi-head attention mechanism to fuse multimodal data with the knowledge graph to extract key features of user capabilities. For example, the "anxiety index" in psychological assessment data is associated with the "emergency handling ability" in the knowledge graph to generate a vector representation of the user's emergency response capabilities. Weighted average calculations dynamically balance the contributions of various data sources. For example, when biological indicators have a higher weight than behavioral logs, the system focuses on the user's physiological state. The capability vector optimization unit ensures that the user's capability model is closely aligned with job requirements by minimizing industry skill gaps. Compared to static scoring models, this module supports real-time updates. The vector is automatically iterated after each user training session, accurately reflecting the changing trends in capabilities.

[0145] In the reinforcement learning recommendation module, the state modeling unit encodes the user's ability vector and knowledge graph into reinforcement learning states. For example, when a user has a "low cardiovascular health score" and "lack of first aid skills," the state vector triggers a recommendation for first aid training. The PPO algorithm introduces a clipping threshold in policy updates to balance exploration and utilization, avoiding the overfitting problem of traditional Q-learning. The reward function design integrates ability improvement, path feasibility, and fatigue. For example, if short-term high-intensity training improves ability but increases fatigue, the system automatically reduces the reward weight for such actions. The path generation unit dynamically expands skill combinations through an entropy-increasing exploration mechanism, for example, recommending a cross-domain skill package of "nutrition + sports rehabilitation," breaking through the rigidity of traditional linear training paths.

[0146] In the virtual training module, the physiological dynamics modeling unit generates personalized parameters based on the user's ability vector. For example, vascular resistance parameters are calculated based on the user's age and blood pressure history, simulating real cardiovascular responses. The scenario simulation unit uses a neural network to map training actions to changes in physiological state. For example, the action of "adjusting insulin dose" directly affects the blood glucose curve of the virtual patient. The real-time feedback unit compares operation results with medical guidelines. For example, when the blood pressure control deviation exceeds 10%, it generates a recommendation of "adjusting medication dosage" or "increasing monitoring frequency." This closed-loop simulation of virtual scenarios allows users to master complex health management skills in a zero-risk environment, addressing the pain points of high cost and high risk of traditional practical training.

[0147] In the evaluation and optimization module, a difference-in-difference model quantifies the causal effects of the training pathway, eliminating the influence of temporal trends and individual differences. For example, of the 30% improvement in competence in the intervention group, 15% can be attributed to the pathway itself. Thompson sampling dynamically allocates resources. For example, new nurses prioritize the combination of "first aid skills + communication skills," while veteran employees focus on "chronic disease management + data analysis." The feedback control unit balances effectiveness and diversity through a multi-objective loss function. A continuous optimization mechanism enables the system to adapt to changes in industry standards. For example, after the introduction of new medical insurance policies, the knowledge graph and reward function are updated simultaneously to ensure the forward-looking nature of the training program.

[0148] A terminal device includes a processor and a memory, wherein the memory stores a computer program, and when the processor executes the computer program, a customized big health talent training system based on artificial intelligence is implemented.

[0149] A storage medium stores a computer program, which, when executed by a processor, implements a large-scale health customized talent training system based on artificial intelligence.

[0150] The terminal device uses the processor to efficiently run multimodal data collection, knowledge graph construction, and reinforcement learning recommendation algorithms, achieving real-time analysis of user biological indicators and behavioral data and dynamic path generation, ensuring millisecond-level response for personalized training programs;

[0151] The storage medium provides standardized program packaging and cross-platform deployment capabilities, supporting medical institutions and health management platforms to flexibly call system functions, such as quickly updating the skill knowledge base through local storage media in an offline environment.
