Abstract

A swapping-based refinement of orthogonal matching pursuit strategies is introduced. The approach is based on recursive forward and backward biorthogonalisation techniques for adapting orthogonal projections. The resulting algorithm, which improves upon orthogonal matching pursuit methods, is fast and easy to implement.
