Abstract: Aiming at the problem that most emotion recognition methods rely on manual feature extraction, a hybrid model based on convolutional neural network (CNN) and bidirectional long short-term memory (Bi-LSTM) network is proposed. Firstly, one-dimensional data is converted into two-dimensional data, and spatial features are extracted by CNN. Then the one-dimensional data is input into Bi-LSTM to obtain temporal features. Finally, the fused spatial and temporal features are input into Softmax classifier to obtain final classification results. Experimental results on DEAP dataset show that CNN and BiLSTM hybrid model has good classification performance, and the accuracy in potency and arousal reaches 88.55% and 89.07%, respectively, proving the proposed model is a feasible and affective EEG emotion classification model.
