Weba Hilbert space Hby means of greedy algorithms and the application of such procedures to the regression problem in statistical learning theory. We improve on the existing theory of convergence rates for both the orthogonal greedy algorithm and the relaxed greedy algo-rithm, as well as for the forward stepwise projection algorithm. For all Webthe Weak Greedy Algorithm with parameter b. It is interesting to compare the rates of convergence of the PGA and the Orthogonal Greedy Algorithm (OGA). We now give a brief definition of the OGA. We define fo 0:= f, Go 0(f,D) = 0 and for m ≥ 1 we inductively define Go m(f,D) to be the orthogonal projection of f onto the span of g(fo 0 ... Websirable to develop theory and algorithms that apply to a broader class of sparsity-constrained learning problems as given in (1). To this end forward greedy selection algo-rithms have been proposed to select out the non-zero en-tries in a sequential way [14, 16]. To make the greedy se-lection procedure more adaptive, [18] proposed a forward- christmas boxes and bags
