Abstract

In this paper, we investigate the efficiency of some kind of Greedy Algorithms with respect to dictionaries from Hilbert spaces. We establish ideal Lebesgue-type inequality for Orthogonal Matching Pursuit also known in literature as the Orthogonal Greedy Algorithm for -coherent dictionaries. We show that the Orthogonal Matching Pursuit provides an almost optimal approximation on the first. DOI: http://dx.doi.org/10.11591/telkomnika.v11i1.1890
