Cooperative greedy pursuit strategies for sparse signal representation by partitioning
Cooperative Greedy Pursuit Strategies are considered for approximating a signal partition subjected to a global constraint on sparsity. The approach aims at producing a high quality sparse approximation of the whole signal, using highly coherent redundant dictionaries. The cooperation takes place by ranking the partition units for their sequential stepwise approximation, and is realized by mean...

Cooperative Orthogonal Matching Pursuit strategies are considered for approximating a signal partition, subjected to a global constraint on sparsity. The approach is designed to produce a high quality sparse approximation of the whole signal, using highly coherent redundant dictionaries.

متن کاملStochastic CoSaMP: Randomizing Greedy Pursuit for Sparse Signal Recovery
In this paper, we formulate the K-sparse compressed signal recovery problem with the L0 norm within a Stochastic Local Search (SLS) framework. Using this randomized framework, we generalize the popular sparse recovery algorithm CoSaMP, creating Stochastic CoSaMP (StoCoSaMP). Interestingly, our deterministic worst case analysis shows that under the Restricted Isometric Property (RIP), even a pur...
متن کاملGreedy Subspace Pursuit for Joint Sparse Recovery
In this paper, we address the sparse multiple measurement vector (MMV) problem where the objective is to recover a set of sparse nonzero row vectors or indices of a signal matrix from incomplete measurements. Ideally, regardless of the number of columns in the signal matrix, the sparsity (k) plus one measurements is sufficient for the uniform recovery of signal vectors for almost all signals, i...
متن کاملOrthogonal Matching Pursuit for Sparse Signal Recovery
We consider the orthogonal matching pursuit (OMP) algorithm for the recovery of a high-dimensional sparse signal based on a small number of noisy linear measurements. OMP is an iterative greedy algorithm that selects at each step the column which is most correlated with the current residuals. In this paper, we present a fully data driven OMP algorithm with explicit stopping rules. It is shown t...
