Remarks

A radial basis function (RBF) is a real-valued function whose value depends only on the distance from the origin, so that ϕ(x) = ϕ(||x||); or alternatively on the distance from some other point c, called a center, so that ϕ(x,c) = ϕ(||x−c||). Any function ϕ that satisfies the property ϕ(x) = ϕ(||x||) is a radial function. The norm is usually Euclidean distance, although other distance functions are also possible.

Examples of radial basis kernels include:
