Multi-dimensional sparse structured signal approximation using split Bregman iterations

Data Structures and Algorithms 2015-03-11 v3 Machine Learning

Abstract

The paper focuses on the sparse approximation of signals using overcomplete representations, such that it preserves the (prior) structure of multi-dimensional signals. The underlying optimization problem is tackled using a multi-dimensional split Bregman optimization approach. An extensive empirical evaluation shows how the proposed approach compares to the state of the art depending on the signal features.
