Detailed Description

A class to perform some of the functions of a Radial Basis Function Network.

Given a set of n training vectors, x_i (i=0..n-1), a set of internal weights are computed. Given a new vector, x, a vector of weights, w, are computed such that if x = x_i then w(i+1) = 1, w(j !=i+1) = 0 The sum of the weights should always be unity. If x is not equal to any training vector, the vector of weights varies smoothly. This is useful for interpolation purposes. It can also be used to define non-linear transformations between vector spaces. If Y is a matrix of n columns, each corresponding to a vector in a new space which corresponds to one of the original training vectors x_i, then a vector x can be mapped to Yw in the new space. (Note: y-space does not have to have the same dimension as x space). This class is equivalent to the basis of thin-plate spline warping.

I'm not sure if this is exactly an RBF network in the original definition. I'll check one day.
