Abstract
- A weak conical greedy algorithm is introduced with respect to an arbitrary positive complete dictionary in a Hilbert space; this algorithm gives an approximation of an arbitrary space element by a combination of dictionary elements with nonnegative coefficients. The convergence of this algorithm is proved and an estimate of the convergence rate for the elements of the convex hull of the dictionary is given. [ABSTRACT FROM AUTHOR]
