Embodiment Construction
[0041] The present invention will be further described below in conjunction with drawings and embodiments.
[0042] As shown in the figure, the EEG feature extraction and classification method based on the deep stack network provided by this embodiment includes the following steps:
[0043] (1) To collect EEG signal data, the EEG signal acquisition device adopts Emotiv EEG signal acquisition instrument. Emotiv contains a total of 16 electrodes, of which CMS and DRL are two reference electrodes, and the electrodes are placed according to the international 10-20 standard electrode placement method. The sampling frequency of the signal is 128Hz. After the collected EEG signal is amplified and filtered, it is transmitted to the computer through the wireless USB receiver. The experiment was carried out in a relatively quiet environment. At the beginning of the experiment (t=0s), the subject sat quietly on the chair and kept in a relaxed state; at t=2s, the subject began to imagine...
