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…
Kurdyka-Lojasiewicz Property of Zero-Norm Composite Functions
Yuqia Wu, Shaohua Pan, Shujun Bi
This paper focuses on a class of zero-norm composite optimization problems. For this class of nonconvex nonsmooth problems, we establish the Kurdyka-Lojasiewicz property of exponen…
An inexact PAM method for computing Wasserstein barycenter with unknown supports
Yitian Qian, Shaohua Pan
Wasserstein barycenter is the centroid of a collection of discrete probability distributions which minimizes the average of the -Wasserstein distance. This paper focuses on…
Equivalent Lipschitz surrogates for zero-norm and rank optimization problems
Yulan Liu, Shujun Bi, Shaohua Pan
This paper proposes a mechanism to produce equivalent Lipschitz surrogates for zero-norm and rank optimization problems by means of the global exact penalty for their equivalent ma…
GEP-MSCRA for computing the group zero-norm regularized least squares estimator
Shujun Bi, Shaohua Pan
This paper concerns with the group zero-norm regularized least squares estimator which, in terms of the variational characterization of the zero-norm, can be obtained from a mathem…
Calibrated zero-norm regularized LS estimator for high-dimensional error-in-variables regression
Ting Tao, Shaohua Pan, Shujun Bi
This paper is concerned with high-dimensional error-in-variables regression that aims at identifying a small number of important interpretable factors for corrupted data from many…
