In plain words: A network scans a song for short sound patterns, then splits into two memory-based branches—one scoring energy, one scoring positivity. It beat the best earlier system on a public music-emotion dataset with far fewer parts, hitting an error of 0.202 for energy.
Abstract
This paper studies the emotion recognition from musical tracks in the 2-dimensional valence-arousal (V-A) emotional space. We propose a method based on convolutional (CNN) and recurrent neural networks (RNN), having significantly fewer parameters compared with the state-of-the-art method for the same task. We utilize one CNN layer followed by two branches of RNNs trained separately for arousal and valence. The method was evaluated using the 'MediaEval2015 emotion in music' dataset. We achieved an RMSE of 0.202 for arousal and 0.268 for valence, which is the best result reported on this dataset.
