Structured sparsity, where the sparse parameters appear in a structured manner, has been a valuable modeling tool in various applications. Computationally, structured sparse penalties are more challenging to numerically cope with, mainly due to their nonsmoothness and non-separability. In this talk we give a systematic overview of some of the re...
