“…They proposed learned ISTA (LISTA), based on unrolling the update steps of ISTA [14] into layers of a feedforward neural network. Subsequent studies have demonstrated the efficacy of this class of modelbased deep learning architectures [33] in compressed sensing and sparse-recovery applications [32], [34], [35], [36], [37], [38], [39], [40], [41], [42], [43]. Deep-unfolding combines the advantages of both data-driven and iterative techniques.…”
