Scaled Fletcher-Revees Method for Training Feed forward Neural Network [PDF]
المجلة العراقية للعلوم الاحصائية, 2011 The training phase of a Back-Propagation (BP) network is an unconstrained optimization problem. The goal of the training is to search an optimal set of connection weights in the manner that the error of the network out put can be minimized.
