A Brain Network Analysis-Based Double Way Deep Neural Network for Emotion Recognition.Constructing reliable and effective models to recognize human emotional states has become an important issue in recent years.  These brain networks are then fed into a subsequent deep neural network block which contains several modules with residual connection and enhanced by channel attention mechanism and spatial attention mechanism.  In the second way of the model, we feed the emotional EEG signals directly into another deep neural network block to extract temporal features. 
Deep Neural Network
To begin with, we transform the emotional EEG signals into five frequency bands by wavelet transform and construct brain networks by inter-channel correlation coefficients.
