Acceleration of rank-constrained spatial covariance matrix estimation for blind speech extraction
Yuki Kubo, Norihiro Takamune, Daichi Kitamura +1
In this paper, we propose new accelerated update rules for rank-constrained spatial covariance model estimation, which efficiently extracts a directional target source in diffuse b…

Efficient Full-Rank Spatial Covariance Estimation Using Independent Low-Rank Matrix Analysis for Blind Source Separation
Yuki Kubo, Norihiro Takamune, Daichi Kitamura +1
In this paper, we propose a new algorithm that efficiently separates a directional source and diffuse background noise based on independent low-rank matrix analysis (ILRMA). ILRMA…
