可穿戴健康设备对实时生物信号处理有强烈需求。传统方法需将边缘设备采集的数据传输至集中式计算单元进行处理,耗时且耗能。类脑计算通过模拟人脑结构与动态,可在延迟和功耗上带来显著优势。本文提出一种新型类脑实现方案:通过事件驱动方式从表面肌电(sEMG)中提取时空脉冲信息,并在脉冲神经网络中引入结构简单、硬件友好型的物理储层计算框架——旋转神经储层(RNR)。该脉冲版旋转神经储层(sRNR)有望为紧凑嵌入式可穿戴系统提供创新解决方案,实现传感器端低延迟、实时处理。系统在公开的大规模sEMG数据库上验证,采用经典机器学习分类器时平均准确率达74.6%,使用脉冲学习规则算法时达80.3%。其中脉冲学习规则可完全以脉冲形式运行,适配类脑芯片,展现出近传感器低延迟处理潜力。

原文摘要 · Abstract (English)

Wearable health devices have a strong demand in real-time biomedical signal processing. However traditional methods often require data transmission to centralized processing unit with substantial computational resources after collecting it from edge devices. Neuromorphic computing is an emerging field that seeks to design specialized hardware for computing systems inspired by the structure, function, and dynamics of the human brain, offering significant advantages in latency and power consumption. This paper explores a novel neuromorphic implementation approach for gesture recognition by extracting spatiotemporal spiking information from surface electromyography (sEMG) data in an event-driven manner. At the same time, the network was designed by implementing a simple-structured and hardware-friendly Physical Reservoir Computing (PRC) framework called Rotating Neuron Reservoir (RNR) within the domain of Spiking neural network (SNN). The spiking RNR (sRNR) is promising to pipeline an innovative solution to compact embedded wearable systems, enabling low-latency, real-time processing directly at the sensor level. The proposed system was validated by an open-access large-scale sEMG database and achieved an average classification accuracy of 74.6\% and 80.3\% using a classical machine learning classifier and a delta learning rule algorithm respectively. While the delta learning rule could be fully spiking and implementable on neuromorphic chips, the proposed gesture recognition system demonstrates the potential for near-sensor low-latency processing.
