Fast Singular Value Shrinkage with Chebyshev Polynomial Approximation Based on Signal Sparsity
Masaki Onuki, Shunsuke Ono, Keiichiro Shirai +1
We propose an approximation method for thresholding of singular values using Chebyshev polynomial approximation (CPA). Many signal processing problems require iterative application…
