Abstract

It belongs to the technical fields of dynamic scheduling of computing resources, biometric compression, and adaptive optimization algorithms using reinforcement learning. Addressing the problems of low computing power reuse rate in fixed time slots, limited BCI transmission bandwidth, and poor adaptability of fixed reward weights, this algorithm comprises three interconnected sub-modules: adaptive time-slot scheduling of load, hierarchical feature compression, and multi-sample reward weight iteration.

Description

[0001] manual 1. Technical Field This invention belongs to the technical fields of dynamic time-sharing scheduling of hardware computing power, lightweight lossless compression of brain-computer biometrics, and adaptive iterative algorithm for triple reward weights in reinforcement learning. It is accompanied by a two-chip on-chip reinforcement learning closed-loop control method. The pure software algorithm is not bound to the hardware structure and can be adapted to all photonic quantum computing chips and intracranial implantable brain-computer devices.

[0002] The existing fixed time slot allocation cannot adapt to the load fluctuations of high and low concentration biological samples, and the upper limit of computing power resource utilization is 92%; the amount of raw EEG and biological three-dimensional feature data is huge, the bandwidth of implanted brain-computer communication is limited, and traditional compression algorithms lose high-risk biological features; the weight of the triple reward function is fixed, and the detection signal-to-noise ratio drops significantly after changing tumor, aging, and neurotransmitter samples, and there is no real-time adaptive iterative update mechanism.

[0003] A global FTO search revealed no integrated algorithm solution that simultaneously integrates three major processes: dynamic time slot allocation for quantitative assessment of biological burden, lossless lightweight compression of high-risk features, and adaptive iteration of multi-sample reward weights. This invention possesses independent and complete inventiveness and can be separately licensed to medical brain-computer interface and AI computing power equipment manufacturers. 2. Background Technology Existing photonic quantum chip computing power scheduling, brain-computer feature processing, and reinforcement learning weight iteration algorithms have three major flaws: 1. Defects in computing power time slot scheduling: The fixed time slot ratio is used to allocate photonic inference and quantum encryption hardware resources. When the load of high-concentration biological sample detection increases, the latency of optical path reconstruction increases significantly; there is no dual-dimensional load quantification evaluation index of signal-to-noise ratio + sample input rate, and the time slot ratio cannot be adjusted in real time; there is a delay due to the heavy load of optical path parameters when switching time slots, which limits the detection throughput; there is no highest priority scheduling logic for medical detection tasks, and large model inference preempts biological detection computing power resources.

[0005] 2. Defects in Brain-Computer Biometric Compression: Traditional general-purpose compression algorithms compress all features uniformly, resulting in the loss of key information in high-risk biometric features such as lesions and aging; compression requires a large amount of floating-point operations, and real-time compression on 20W on-chip hardware has high latency; there is no synchronous parallel time-series process for optical path operation and feature compression, which doubles the hardware computing power; there is no feedback branch to optimize the reinforcement learning network for compression errors.

[0006] 3. Defects of reinforcement learning reward weight iteration: The weight ratio of the triple reward (signal-to-noise ratio, latency, and power consumption) is fixed, which is only suitable for a single type of biological sample; there is no automatic weight correction mechanism for samples with high and low molecular concentrations; there is no cold start fast initialization strategy for new and unknown biological samples; the computational power consumption of floating-point gradient calculation for weight iteration is high, and it is difficult for low-power on-chip hardware to continuously iterate and optimize.

[0007] The existing prior art documents only disclose individual sub-algorithms such as computing power scheduling, feature compression, and reward weight optimization, without integrating them into a unified closed-loop control algorithm process. There is no complete algorithm patent scheme that can be independently licensed. 3. Summary of the Invention 3.1 Purpose of the Invention To address the three major shortcomings of existing algorithms—low utilization rate of computing power in fixed time slots, high risk of losing biological information due to brain-computer feature compression, and inability of triple reward weights to adapt to automatic iteration of multiple samples—this invention provides an integrated control algorithm based on biological load adaptive time slot scheduling, lightweight compression of brain-computer features, and multi-sample reward weight iteration. The pure algorithm has no hardware binding restrictions and simultaneously achieves dynamic optimal allocation of computing resources, lossless low-bandwidth feature transmission between brain and computer, and automatic adaptation of optical path optimization for multiple samples. This further improves the overall computing power utilization rate, multi-marker detection performance, and intracranial brain-computer communication adaptation capability, filling a global gap in integrated scheduling and optimization algorithms for biological detection and brain-computer fusion.

[0009] 3.2 Complete Algorithm Technical Solution A control algorithm integrating adaptive time-slot scheduling based on biological load, lightweight compression of brain-computer features, and multi-sample triple reward weight iteration is proposed. The on-chip AI kernel cyclically executes three linked sub-algorithm modules: adaptive dynamic time-slot scheduling module based on biological load, graded lossless lightweight compression module based on brain-computer biometrics, and adaptive iteration module based on multi-sample triple reward weight. The three modules communicate with each other and operate synchronously.

[0011] Module 2: Brain-Computer Biometric Grading Lossless Lightweight Compression Module 1.

Lightweight discrete wavelet single-step compression operator, occupying only 1 bit of intermediate buffer parameters, adapted to on-chip low-power hardware; 3. Compression computation and photonic three-channel feature extraction are performed synchronously and in parallel, sharing hardware computing resources; 4. A real-time feedback branch for compressed errors is used to transmit error values ​​back to the reinforcement learning network and dynamically adjust the weights of the reward function. 5. Standardized low-bandwidth brain-computer interface output format, compressed data adapted to the narrowband transmission bus of intracranial implantable devices; 6. During device sleep periods, background batch caching and compression reduce peak power consumption for real-time computing.

Weight iteration gradient binarization lightweight calculation significantly reduces iteration computational overhead; 5. A novel cold-start rapid initialization strategy for unknown biological samples, achieving weight convergence optimization in a short time; 6. The weight update results directly map to the photonic waveguide topology reconstruction parameters, eliminating the need for secondary format conversion.
