| Abstract(in English) | This paper proposes a novel method for source number estimation based on the clustering of source activity sequences. The method first derives source activity sequences through clustering-based blind source separation using more clusters than the maximum anticipated number of sources. It then classifies all source activity sequences simultaneously in all frequency bins, and finally obtains a source number estimate as the number of clusters in which activity concentrates. An experiment shows that the proposed method enumerates sources accurately even in reverberant and underdetermined conditions without using a sparse prior as per [1]. |
