An Analytical Method of The References of 3 Layers Feed-Forward Network

This article presents an analytical method of the references of 3 layers feed forward network. In the meantime, an adequate condition is given for the number of nodes in the hidden layer for a 3 layers feed forward network to precisely memorize a set of samples. We can also use this references which is calculated by the analytical method as the initial references of BP algorithm. The simulation proves that the above method is effective.
