Improving A*OMP: Theoretical and Empirical Analyses With a Novel Dynamic Cost Model
Nazim Burak Karahanoglu, Hakan Erdogan
Best-first search has been recently utilized for compressed sensing (CS) by the A* orthogonal matching pursuit (A*OMP) algorithm. In this work, we concentrate on theoretical and em…

A* Orthogonal Matching Pursuit: Best-First Search for Compressed Sensing Signal Recovery
Nazim Burak Karahanoglu, Hakan Erdogan
Compressed sensing is a developing field aiming at reconstruction of sparse signals acquired in reduced dimensions, which make the recovery process under-determined. The required s…
