Thought this was cool: Complex Matrix Factorization Toolbox – implementation –

leave a comment »



I really don’t know why matrix factorization is synonymous to NMF but it bothers me a little. As if positivity constraints were the only thing that really mattered. Anyway, enough of the rant, here is an NMF related Complex Matrix Factorization Toolbox I spotted thanks to the Google. It is here.

Complex Matrix Factorization Toolbox

We acknowledge the support of the U.S. Air Force Office of Scientific Research and the U.S. Office of Naval Research in the development of this toolbox.

Overview

This toolbox contains all of the state-of-the-art methods of complex matrix factorization, including complex matrix factorization with intra-source additivity constraints (CMFWISA) and complex probabilistic latent component analysis (CPLCA). These methods are currently optimized for use with a short time Fourier transform (STFT) for single-channel source separation of audio, but can be used for any complex-valued matrix data.
