Radial basis function

Two unnormalized Gaussian radial basis functions in one input dimension. The basis function centers are located at x1=0.75 and x2=3.25.

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