Wikipedia Overview
In functional analysis, a reproducing kernel Hilbert space (RKHS) is a Hilbert space of functions in which point evaluation is a continuous linear functional. Specifically, a Hilbert space of functions from a set is an RKHS if the point-evaluation functional , , is continuous for every . Equivalently, is an RKHS if there exists a function such that, for all ,The function is then called the reproducing kernel, and it reproduces the value of at via the inner product.
