The invention provides a bridged
convolutional neural network-based emotion electroencephalogram
signal classification method, which comprises the following steps of: firstly, extracting electroencephalogram
signal bottom-layer features by using a first convolutional layer of V3, taking the electroencephalogram
signal bottom-layer features as the input of V1, and inputting the V1 into a third convolutional layer to extract middle-layer features after the V1 is down-sampled by a second
pooling layer; and the middle-layer feature is used as the input of V2, is down-sampled by the fourth poolinglayer of V3 and then is input to the fifth
convolution layer of V3 to extract the high-layer feature. And then, the three
layers of features are respectively subjected to
dimensionality reduction andthen are input into an eighth full-connection layer of the V3 for fusion, and finally, the three
layers of features enter a Softmax layer for classification. And comparing the
classification result with the actual
label, calculating a loss value, and then updating the
convolution kernel and the connection weight by using a
back propagation algorithm. According to the method, the electroencephalogram
signal classification accuracy can be high, and the recognition result is superior to that of a traditional
machine learning method and a traditional CNN model.
