Genetic Algorithm Optimized Structured Dictionary for Discriminative Block Sparse Representation

This paper presents a few innovations towards learning a discriminative block-structured dictionary. The learning process of such a dictionary is broadly divided into two steps: block formation and dictionary update. In the existing works on block structure estimation, it is assumed that the maximum...
