Perfect reconstruction of sparse signals using nonconvexity control and one-step RSB message passing arXiv:2512.17426v1 Announce Type: new Abstract: We consider sparse signal reconstruction via minimization of the smoothly clipped absolute deviation (SCAD) penalty, and develop one-step replica-symmetry-breaking (1RSB) extensions of approximate message passing (AMP), termed 1RSB-AMP. Starting from the 1RSB formulation of belief propagation, we…
