Introduction:- Neural network are simplified model of the biological nervous system. Neural network is a highly interconnected network of a large number of processing elements called neurons in an architecture inspired by the brain. Neural networks exhibit
The Counterpropagation Network (CPN), introduced by Robert Hecht-Nielsen in 1987, is a hybrid feedforward neural network that combines unsupervised competitive learning with supervised outstar learning. Unlike pure backpropagation networks, CPN trains in two
