Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents positive semidefinite tensor factorization (PSDTF) that is a natural extension of nonnegative matrix factorization (NMF) and shows that PSDTF outperforms NMF in source separation of single-channel audio signals. We propose a PSDTF-based method that can directly separate a given mixture signal into source signals in the time domain without explicitly dealing with phase information. In addition, a nonparametric Bayesian extension of PSDTF is feasible by using the gamma process in a similar manner to NMF.
