Perfect reconstruction of sparse signals using nonconvexity control and one-step RSB message passing

Xiaosi Gu, Ayaka Sakata, Tomoyuki Obuchi

We consider sparse signal reconstruction via minimization of the smoothly clipped absolute deviation (SCAD) penalty, and develop one-step replica-symmetry-breaking (1RSB) extension…
