Abstract(in Japanese) (See Japanese page)
Abstract(in English) It is known that block permutation occurs in the separated signals obtained by independent low-rank matrix analysis. Recently, a new method that focuses on the spectrogram consistency of the signal has been proposed to induce low-rank property on the projected spectrogram of the separated signal onto the spectrogram-consistent space. In contrast to the conventional methods, which do not care how far the spectrogram of the separated signal is from the spectrogram-consistent space, we design a regularization term that induces the spectrogram of the separated signal itself to be consistent. For the designed optimization problem, we derive the update rules based on the auxiliary function method. We verify the effectiveness of the proposed method by the experiment.
