Every critical point of an L0 composite minimization problem is a local minimizer

Xue Feng, Chunlin Wu

Nowadays, L0 optimization model has shown its superiority when pursuing sparsity in many areas. For this nonconvex problem, most of the algorithms can only converge to one of its c…

An Efficient and Globally Convergent Algorithm for $ℓ_{p, q}$ - $ℓ_{r}$ Model in Group Sparse Optimization

Yunhua Xue, Yanfei Feng, Chunlin Wu

Group sparsity combines the underlying sparsity and group structure of the data in problems. We develop a proximally linearized algorithm InISSAPL for the non-Lipschitz group spars…
