Nonnegative matrix factorization (NMF) is a powerful technique of extracting meaningful patterns from an observed matrix and has been used for many applications in the audio signal processing field. In this article, the principle of NMF and some extensions based on a complex generative model are reviewed. Also, their application to audio source separation is presented.
