Approximation by Perceptron Networks
Abstract
In this paper we survey our recent results on properties of approximation by linear combinations of characteristic functions of half-spaces. We focus on existence of best approximation, impossibility of choosing among best approximations a continuous one, estimates of rates of approximation by linear combinations of "n" characteristic functions of half-spaces and integral representation as a linear combination of a continuum of half-spaces.
