Multichannel nonnegative matrix factorization in convolutive mixtures. With application to blind audio source separation
Found in: Acoustics, Speech, and Signal Processing, IEEE International Conference on
By Alexey Ozerov, Cedric Fevotte
Issue Date:April 2009
pp. 3137-3140
We consider inference in a general data-driven object-based model of multichannel audio data, assumed generated as a possibly under-determined convolutive mixture of source signals. Each source is given a model inspired from nonnegative matrix factorizatio...
 
A tempering approach for Itakura-Saito non-negative matrix factorization. With application to music transcription
Found in: Acoustics, Speech, and Signal Processing, IEEE International Conference on
By Nancy Bertin, Cedric Fevotte, Roland Badeau
Issue Date:April 2009
pp. 1545-1548
In this paper we are interested in non-negative matrix factorization (NMF) with the Itakura-Saito (IS) divergence. Previous work has demonstrated the relevance of this cost function for the decomposition of audio power spectrograms. This is in particular d...
