Alternating Iteratively Reweighted $ℓ_{1}$ and Subspace Newton Algorithms for Nonconvex Sparse Optimization

Hao Wang, Xiangyu Yang, Yichen Zhu

This paper presents a novel hybrid algorithm for minimizing the sum of a continuously differentiable loss function and a nonsmooth, possibly nonconvex, sparse regularization functi…

Minimization Over the Nonconvex Sparsity Constraint Using A Hybrid First-order method

Xiangyu Yang, Hao Wang, Yichen Zhu +1

We investigate a class of nonconvex optimization problems characterized by a feasible set consisting of level-bounded nonconvex regularizers, with a continuously differentiable obj…
