论文摘要

上肢运动分类将输入信号映射到目标活动,是控制康复机器人技术的关键基础。分类器接受了康复系统的培训,以理解上肢无法正常工作的患者的欲望。肌电图(EMG)信号和脑电图(EEG)信号广泛用于上肢运动分类。通过分析实时脑电图和EMG信号的分类结果,系统可以理解用户的意图,并预测人们希望执行的事件。因此,它将为用户提供外部帮助。但是,实时脑电图和EMG数据收集过程中的噪声污染了数据的有效性,这破坏了分类性能。此外,并非所有患者由于肌肉损伤和神经肌肉疾病而处理强大的EMG信号。为了解决这些问题,本文探讨了脑电图和EMG信号分类的不同功能提取技术和机器学习以及深度学习模型,并提出了一种新颖的决策级多电磁融合技术,以将EEG信号与EMG信号整合在一起。该系统从两个来源检索有效的信息,以理解和预测用户的愿望,从而帮助。通过在包含同时记录的脑电图和EMG信号的公开途径数据集中测试提出的技术,我们设法结论了新型系统的可行性和有效性。

Upper limb movement classification, which maps input signals to the target activities, is a key building block in the control of rehabilitative robotics. Classifiers are trained for the rehabilitative system to comprehend the desires of the patient whose upper limbs do not function properly. Electromyography (EMG) signals and Electroencephalography (EEG) signals are used widely for upper limb movement classification. By analysing the classification results of the real-time EEG and EMG signals, the system can understand the intention of the user and predict the events that one would like to carry out. Accordingly, it will provide external help to the user. However, the noise in the real-time EEG and EMG data collection process contaminates the effectiveness of the data, which undermines classification performance. Moreover, not all patients process strong EMG signals due to muscle damage and neuromuscular disorder. To address these issues, this paper explores different feature extraction techniques and machine learning and deep learning models for EEG and EMG signals classification and proposes a novel decision-level multisensor fusion technique to integrate EEG signals with EMG signals. This system retrieves effective information from both sources to understand and predict the desire of the user, and thus aid. By testing out the proposed technique on a publicly available WAY-EEG-GAL dataset, which contains EEG and EMG signals that were recorded simultaneously, we manage to conclude the feasibility and effectiveness of the novel system.
