Relaxed Sparse Eigenvalue Conditions for Sparse Estimation via Non-convex Regularized Regression

14 Jun 2013Zheng PanChangshui Zhang

Non-convex regularizers usually improve the performance of sparse estimation in practice. To prove this fact, we study the conditions of sparse estimations for the sharp concave regularizers which are a general family of non-convex regularizers including many existing regularizers... (read more)
