| Abstract(in English) | The multi-channel nonnegative matrix factorization (MNMF) is an extension of the single-channel nonnegative matrix factorization (SNMF) to multi-channel observations which can be used for blind source separation of multichannel audio signals. In our previous work, we proposed an initial value setting method for spatial correlation matrices and confirmed that the convergence performance was improved. In this paper, we further investigate the performance of the proposed methodunder various conditions. |
