Matrix rank estimation is a classical problem with many applications in statistical signal processing. In this letter, a logistic function based thresholding of the singular values is proposed for the rank estimation purpose. Parameters of the proposed shrinkage function are tuned using Stein’s unbiased risk estimator. The proposed method is shown to outperform the state-of-the-art methods in terms...
In this work, we have studied the effectiveness of recently proposed warp factor estimation method based on correlation between the pitch frequency and the warp factor for speaker normalization. Our study shows that estimation of warp factors using maximum a posteriori criterion by exploiting the statistics from the pitch based warp factor estimation approach results in 12.5% relative improvement...
