| Abstract: | The author has investigated why the converging process of a multilayer neural network with back error propagation learning rule is very slow. A modified excitation function F(x) is given. The step adaptation strategy, output feedback suppression strategy and pattern vector preprocessing strategy are also presented. The learning process was speeded up significantly. Finally the computer simulation results are given. |
