Hierarchical matching pursuit

Web2 de mar. de 2016 · 3.1 Orthogonal matching pursuit (OMP) and kernel OMP (KOMP) It is well known that OMP is one of the greedy algorithms for sparse approximation due to its simplicity and efficiency. Since the optimization problem ( 1 ) can be solved in an alternating fashion, OMP is capable of computing sparse codes when this problem is decoupled to …
