Emotion guidance system based on brain wave music generation of LongFormer

The invention relates to an emotion guidance system and method for brain wave music generation based on LongFormer, and the method comprises the steps: firstly, a user selects an expected emotion state and a track type which a user wants to listen to in an emotion multi-dimensional space, recognizes the current emotion of the user through an electroencephalogram signal, and projects the emotion to the emotion multi-dimensional space; according to the method, a music style type selected by a user and a current user emotion expected migration vector are used as features to be input into a brain wave music generation model of LongFormer, music meeting requirements is automatically generated and played in an autoregression mode, and then based on the real-time emotion dynamic change condition reflected by current electroencephalogram signal data, the emotion migration prediction of the user is realized. And automatically generating a next suitable playing song. According to the method, the ...
