Non negative matrix factorization for music emotion classification
Classification of emotion is a fundamental problem in music information retrieval where it addresses the query and retrieval of desirable types of music from large music data set. Until recently, there are only few works on music emotion classification that are carried out by incorporating instrumen...

Until recently, there are only few works on music emotion classification that are carried out by incorporating instrumental and vocal timbre.
