EEG signals have been widely used in emotion recognition in recent years. However, a great challenge still exists for the practical applications of cross-subject emotion recognition. Inspired by recent neuroscience studies and the advantage of the DE feature applied in EEG emotion recognition, we proposed a combined DE feature and contrastive learning method to tackle the cross-subject emotion recognition problem. The proposed model can minimize the inter-subject differences by maximizing the similarity in EEG signal representations across subjects when they receive the same emotional stimuli in contrast to different ones and gain a better encoding. Finally, we conducted extensive experiments on SEED and SEED-IV. The cross-subject emotion recognition accuracy is 84.72 on the SEED and 69.24 on the SEED-IV. It experimentally verified the effectiveness of the model.
