A proximal MM method for the zero-norm regularized PLQ composite optimization problem
Dongdong Zhang, Shaohua Pan, Shujun Bi
This paper is concerned with a class of zero-norm regularized piecewise linear-quadratic (PLQ) composite minimization problems, which covers the zero-norm regularized -loss…

Subregularity of subdifferential mappings relative to the critical set and KL property of exponent 1/2
Shaohua Pan, Yulan Liu
For a proper extended real-valued function, this work focuses on the relationship between the subregularity of its subdifferential mapping relative to the critical set and its KL p…
