This paper proposes an effective sequential initialization for multichannel nonnegative matrix factorization to address the difficulty of initial value dependency of the conventional method. The proposed method sets initial values of parameters from those obtained for the smaller number of channels. The experimental results of music separation show that the proposed method outperforms the conventional method.
