Music emotion understanding by computer based on BP neural network
Jun Liu, Min Huang, Jun Liu · 2017
In order to enable the computer to recognize the emotion expressed in the music, a new method was developed in this paper. Firstly, we divided the emotion space into four parts according to Thayer model. Secondly, we extracted eight features from the music and finally a BP neural network was created to classify the music in the emotion space. The result shown the computer recognition is high coincident with the expert recognition and the reliability of the method was proved.
