Fig. 4From: Learning-based robust speaker counting and separation with the aid of spatial coherenceScatter plots of the eigenvalues corresponding to the observations with \(J \in \left\{1, 2, 3, 4\right\}\) speakers. Each cross with different color represents an observation corresponding to different number of speakers. The left row shows the result with the correlation matrix W and the right row is the result with the coherent matrix \(\mathbf{W}\)Â Â Back to article page
