Structured Sparsity: Theory, Algorithms and Applications

.Introduction

This work investigates a new learning formulation called structured sparsity, which is a natural extension of the standard sparsity concept in
statistical learning and compressive sensing. By allowing arbitrary structures on the feature set, this concept generalizes the group sparsity idea. A general theory is developed for learning with structured sparsity, based on the notion of coding complexity associated with the structure. Moreover, efficient algorithms are developed to solve the structured sparsity problems. It is general enough to be applied in differnt applications to achieve bette performance.
