Anderson Acceleration for Nonsmooth Fixed Point Problems
Wei Bian, Xiaojun Chen
We give new convergence results of Anderson acceleration for the composite fixed point problem. We prove that Anderson(1) and EDIIS(1) are q-linear convergent with a smaller…
Fast inertial dynamic algorithm with smoothing method for nonsmooth convex optimization
Xin Qu, Wei Bian
In order to solve the minimization of a nonsmooth convex function, we design an inertial second-order dynamic algorithm, which is obtained by approximating the nonsmooth function b…
Accelerated forward-backward method with fast convergence rate for nonsmooth convex optimization beyond differentiability
Wei Bian, Fan Wu
We propose an accelerated forward-backward method with fast convergence rate for finding a minimizer of a decomposable nonsmooth convex function over a closed convex set, and name…
DC algorithms for a class of sparse group regularized optimization problems
Wenjing Li, Wei Bian, Kim-Chuan Toh
In this paper, we consider a class of sparse group regularized optimization problems. Firstly, we give a continuous relaxation model of the considered problem and establis…
Smoothing fast iterative hard thresholding algorithm for regularized nonsmooth convex regression problem
Fan Wu, Wei Bian, Xiaoping Xue
We investigate a class of constrained sparse regression problem with cardinality penalty, where the feasible set is defined by box constraint, and the loss function is convex, but…
