Abstract (in Japanese) (See Japanese page) 
(in English) We propose a blind source separation (BSS) algorithm using a priori information of the mixing process based on the state-of-the-art method for BSS, called independent low-rank matrix analysis (IRLMA). Even though ILRMA can provide the best source separation performance, it can be sometimes degraded by an inappropriate initial valuefor the algorithm. Tosolvethis problem, weexploit sparsityof impulse responses of the mixing process. Simulations using publicly available impulse responses show that the proposed method outperforms ILRMA with respect to evaluation measures of SDR, SIR, and SAR.
