Representer theorem - Wikipedia
In mathematics, specifically functional analysis, Mercer's theorem is a representation of a symmetric positive-definite function on a square as a sum of a convergent sequence of product functions. This theorem, presented in (Mercer 1909), is one of the most notable results of the work of James Mercer … Meer weergeven To explain Mercer's theorem, we first consider an important special case; see below for a more general formulation. A kernel, in this context, is a symmetric continuous function Meer weergeven The following is immediate: Theorem. Suppose K is a continuous symmetric positive-definite kernel; TK has a sequence … Meer weergeven • Kernel trick • Representer theorem • Spectral theory Meer weergeven We now explain in greater detail the structure of the proof of Mercer's theorem, particularly how it relates to spectral theory of compact operators. • The … Meer weergeven Mercer's theorem itself is a generalization of the result that any symmetric positive-semidefinite matrix is the Gramian matrix of a set of vectors. The first generalization replaces the interval [a, b] with any compact Hausdorff space and … Meer weergeven Web{"content":{"product":{"title":"Je bekeek","product":{"productDetails":{"productId":"9200000082899420","productTitle":{"title":"BAYES Theorem","truncate":true ...
