Abstract (in Japanese) (See Japanese page) 
(in English) Independent low-rank matrix analysis (ILRMA) is the state-of-the-art technique for blind source separation under the overdetermined situation. Recently, some methods have proposed that focus on the spectrogram consistency of the separated signal in order to improve the separation performance. One of those methods introduces the regularization term that directly induces the separated signal to be consistent into ILRMA. Whereas in the conventional mothod, the regularization term is designed to be independent of the observed signal, the regularization term is designed to be specific to the observed signal in this study. For the obtained optimization problem, we drive a new update rule based on the majorization-minimization algorithm with an auxiliary function that is an extension of that used in conventional method. Finally, a numerical experiment is conducted to verify the separation performance.
