BP learning algorithm

Neural network learning algorithms BP = Back-Propagation Delta = Delta Rule QP = Quick-Propagation RP = Rprop ART = Adaptive Resonance Theory, CP = Counter-Propagation. 

The backpropagation (BP) network is the most commonly used FNN. Its structure is the same as that shown in Fig. 2.6 except that it can contain more than one hidden layer. A BP algorithm is used for BP network learning, which is described in detail below. 

BP networks tend to get stuck in local minima. Although the algorithms mentioned earlier that speed up learning help to overcome this tendency, it may be best to use a different network if you think this is a serious problem. The networks listed in the second to last paragraph for regression and classification problems are possible options.
