What Does Radial Basis Function Network (RBF Network) Mean?

A radial basis function network is a type of supervised artificial neural network that uses supervised machine learning (ML) to function as a nonlinear classifier. Nonlinear classifiers use sophisticated functions to go further in analysis than simple linear classifiers that work on lower-dimensional vectors.

Using a set of prototypes along with other training examples, neurons look at the distance between an input and a prototype, using what is called an input vector.
