Inexact Proximal-Gradient Methods with Support Identification
Yutong Dai, Daniel P. Robinson
We consider the proximal-gradient method for minimizing an objective function that is the sum of a smooth function and a non-smooth convex function. A feature that distinguishes ou…

A Subspace Acceleration Method for Minimization Involving a Group Sparsity-Inducing Regularizer
Frank E. Curtis, Yutong Dai, Daniel P. Robinson
We consider the problem of minimizing an objective function that is the sum of a convex function and a group sparsity-inducing regularizer. Problems that integrate such regularizer…
