A Tight Bound of Hard Thresholding

Abstract

This1 paper is concerned with the hard thresholding technique which sets all but the k largest absolute elements to zero. We establish a tight bound that quantitatively characterizes the deviation of the thresholded solution from a given signal. Our theoretical result is universal in the sense that it holds for all choices of parameters, and the underlying… (More)
