Abstract

Consider a nonlinear transform of x in to Hilbert space H and assume that the dot product between and in H is given by < , >= K(x, x'). The aim of this paper is to propose a mathematical technique to take screen shots of the multivariate dataset mapped to Hilbert space H, particularly suited to Gaussian kernel , which is defined by , > 0. Several numerical examples are given.
