Abstract (in Japanese) (See Japanese page) 
(in English) This paper addresses a stereo signal separation problem and gives an experimental study on optimal divergence for superresolution-based supervised nonnegative matrix factorization (NMF). In the previous studies, a hybrid method concatenating superresolution-based supervised NMF after directional clustering has been proposed for multichannel signal separation. In this paper, we derive generalized update rules for superresolution-based supervised NMF based on beta-divergence criterion, and discuss the optimal divergence for the hybrid method.
