The so-called radial basis function, in fact, is some kind of scalar function along radial symmetry. A monotone function, usually defined as a Euclidean distance between any point in space X to a central C, can be recorded as K (| | x-c| |), the effect is often local, that is

RBF network originates from the radial basis function method of multivariate interpolation in numerical analysis, which has the best approximation characteristic which is not available in traditional BP network. The three-layer RBF network has the ability to approximate any function. It is assumed that the number of nodes in the hidden layer of the input nodes in the network is n,l,m. The function of the
