Binary iterative hard thresholding

WebMar 21, 2024 · We provide a theoretical study of the iterative hard thresholding with partially known support set (IHT-PKS) algorithm when used to solve the compressed sensing recovery problem. Recent work has shown that IHT-PKS performs better than the traditional IHT in reconstructing sparse or compressible signals. However, less work has … Web3 Iterative Hard-thresholding Method In this section we study the popular projected gradient descent (a.k.a iterative hard thresholding) method for the case of the feasible set being the set of sparse vectors (see Algorithm 1 for pseu-docode). The projection operator P s(z), can be implemented efficiently in this case by projecting
