A. Dingankar et Iw. Sandberg, A NOTE ON ERROR-BOUNDS FOR APPROXIMATION IN INNER-PRODUCT SPACES, Circuits, systems, and signal processing, 15(4), 1996, pp. 515-518
In a recent paper a method is described for constructing certain appro
ximations to a general element in the closure of the convex hull of a
subset of an inner product space. This is of interest in connection wi
th neural networks. Here we give an algorithm that generates simpler a
pproximants with somewhat less computational cost.
