A '''probabilistic neural network (PNN)''' is a [[feedforward neural network]], which was derived from the [[Bayesian network]]<ref>http://herselfsai.com/2007/03/probabilistic-neural-networks.html</ref> and a statistical algorithm called [[Kernel Fisher discriminant analysis]].<ref>http://www.psi.toronto.edu/~vincent/research/presentations/PNN.pdf</ref> It was introduced by D.F. Specht in the early 1990s.<ref name=Specht1990>{{Cite doijournal | last1 = Specht | first1 = D.
