Abstract (in Japanese) (See Japanese page) 
(in English) Nonnegative Matrix Factorization (NMF) is one of the technique used for separation of an audio mixture that consists of multiple instrumental sources. The conventional supervised NMF has a critical problem that a mismatch between the basis trained in advance and the target actual sound reduces the accuracy of separation.
To solve this problem, we propose a new advanced supervised NMF that includes a deformable term for the trained basis and constrained conditions for making the basis fit into the target sound. The results of the experiment using real instruments show that the proposed method significantly improves the accuracy of separation compared with the conventional method.
