Example Embodiment
[0035] Such as figure 1 and figure 2 As shown, a brain eM emotional identification system based on the learning neighboring matrix includes the following steps:
[0036] Step 1, the acquisition, processing, and division of the data: convert the extracted EEG signal into M × N feature data matrix x∈R M×N Where m is the number of brain electrodes, n is the number of segments of the frequency band; data division, part of the data as a training set, and another part of the data is a validation set.
[0037] In the present embodiment, the specific process of data acquisition is: the subject head wears the EMG collection device, viewing a video that can cause different emotions, to view the corresponding eElectronic signal when viewing the video, and performs the obtained EEG information Noise reduction, pretreatment, extraction characteristics. EEG signal acquisition equipment adopts NEUROSCAN's 64-director-e-electric collection equipment, because the data collected by the partial elec...
