Webprojections. However, a critical challenge in the case of overlapping groups is the projection onto the set of group-sparse vectors is NP-hard in general. To alleviate this issue, we use the connection between submodularity and overlapping group projections and a greedy selection based projection is at least good enough. 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 ... pop in connector
