Generalized regression neural network (GRNN) is a variation to radial basis neural networks (RBFNN). GRNN was suggested by D.F. Specht in 1991.[1].
GRNN can be used for regression, prediction, and classification. GRNN can also be a good solution for online dynamic systems.
GRNN represents an improved technique in the neural networks based on the non-paramertic regression. The basic idea is that every training sample will represents a mean to a radial basis neuron[2].
Mathematical represntion of the GRNN[3]:
where is the prediction value of input .
where is the distance between the training samples and the input .
GRNN has been implemented in many software including Matlab and R- programming language.
