Rate of Convergence of Greedy Algorithms


This paper deals with the approximation of elements of a real separable Hilbert space H with inner product (·,·). A subset of elements D is contained in H is called a dictionary if ‖g‖ = 1 for any g ∈ D and, moreover, the closure of the linear hull of D in H coincides with H. For f ∈ H, by g = g(f) ......
