By replacing the sigmoid activation function often used in neural networks with an exponential function, a probabilistic neural network (PNN) that can compute nonlinear decision boundaries which approach the Bayes optimal is formed. Alternate activation functions having similar properties are also discussed.

A probabilistic neural network (PNN) is a feedforward neural network, which is widely used in classification and pattern recognition problems. In the PNN algorithm, the parent probability distribution function (PDF) of each class is approximated by a Parzen window and a non-parametric function. Then, using PDF of … Visa mer PNN is often used in classification problems. When an input is present, the first layer computes the distance from the input vector to the training input vectors. This produces a vector where its elements indicate how close … Visa mer • probabilistic neural networks in modelling structural deterioration of stormwater pipes. • probabilistic neural networks method to gastric endoscope samples diagnosis based on … Visa mer There are several advantages and disadvantages using PNN instead of multilayer perceptron. • PNNs are much faster than multilayer perceptron networks.
