Fig. 3From: New inexact explicit thresholding/shrinkage formulas for inverse problems with overlapping group sparsityComparison between our method and the MM method for one-dimensional signal denoising. Second row to bottom row, from top to bottom, results of the MM method, our Formula (I), our Formula (II) respectively, absolute error, and function value history. From left to right, β=3,10,15 respectivelyBack to article page
