The functions drawn from any Gaussian process are one example of an RKHS. Deeper understanding. We’ll first try to understand the “Hilbert space” part of “reproducing kernel Hilbert space,” and then investigate the “reproducing kernel” part.

WebTheorem 1. A Hilbert space Hof functions over a non-empty set Xis an RKHS if and only if there exists a kernel k, called the reproducing kernel of Hsuch that 1. k(;x) 2H8x2X 2. hf;k(;x)i= f(x) 8f2H8x2X Proof. Suppose His an RKHS. Then xis continuous for every x2Xso by Riesz repre-sentation theorem there exists ˚ x2Hsuch that x(f) = hf;˚ xi. Web1 Introduction This note introduces a particular kind of Hilbert space known as a reproducing kernel Hilbert space (RKHS). We will establish connections with kernels, de ned previously, and show that kernels and RKHSs are in one-to-one correspondence. This material is largely drawn from Chapter 4 of [1], although some results are gina wilson all things algebra 2015 unit 2
