Sparse recovery via nonconvex regularized $M$ -estimators over $ℓ_{q}$ -balls

Xin Li, Dongya Wu, Chong Li +2

In this paper, we analyse the recovery properties of nonconvex regularized $M$ -estimators, under the assumption that the true parameter is of soft sparsity. In the statistical aspe…

Convergence Analysis of Gradient Algorithms on Riemannian Manifolds Without Curvature Constraints and Application to Riemannian Mass

Chong Li, Xiangmei Wang, Jinhua Wang +1

We study the convergence issue for the gradient algorithm (employing general step sizes) for optimization problems on general Riemannian manifolds (without curvature constraints).…
