Super Greedy Type Algorithms and Applications In Compressed Sensing
<p>In this manuscript we study greedy-type algorithms such that at a greedy step we pick several dictionary elements contrary to a single dictionary element in standard greedy-type algorithms. We call such greedy algorithms super greedy type algorithms. In the general setting, we propose several …

Efficient and guaranteed algorithms for sparse inverse problems
… guarantees are derived using a so-called restricted isometry property (RIP), which has only been shown to hold under ideal assumptions. For example, the sampling from the frame needs to be independent and identically distributed with the uniform distribution, and the frame must be tight. …
