Complexity and convergence analysis of a single-loop SDCAM for Lipschitz composite optimization and beyond
Hao Zhang, Naoki Marumo, Ting Kei Pong +1
We develop and analyze a single-loop algorithm for minimizing the sum of a Lipschitz differentiable function , a prox-friendly proper closed function (with a closed domain o…
A single-loop proximal-conditional-gradient penalty method
Hao Zhang, Liaoyuan Zeng, Ting Kei Pong
We consider the problem of minimizing a convex separable objective (as a separable sum of two proper closed convex functions and ) over a linear coupling constraint. We assu…
Analysis and algorithms for some compressed sensing models based on L1/L2 minimization
Liaoyuan Zeng, Peiran Yu, Ting Kei Pong
Recently, in a series of papers [32,38,39,41], the ratio of and norms was proposed as a sparsity inducing function for noiseless compressed sensing. In this paper…
Iteratively reweighted algorithms with extrapolation
Peiran Yu, Ting Kei Pong
Iteratively reweighted algorithm is a popular algorithm for solving a large class of optimization problems whose objective is the sum of a Lipschitz differentiable loss fu…
