This paper proposes an epigraphical relaxation (ERx) technique for non-proximable mixed
norm minimization. Mixed norm regularization methods play a central role in signal …

This paper proposes an epigraphically-relaxed linearly-involved generalized Moreau-
enhanced (ER-LiGME) model for layered mixed norm regularization. Group sparse and low …

This paper presents a novel framework for the continuation method of model predictive
control based on optimal control problem with a nonsmooth regularizer. Via the proximal …

This letter develops a framework for differentiating sparse optimal control inputs with respect
to cost parameters. The difficulty lies in the non-smoothness induced by a sparsity …
