| Abstract: | A novel approach to speed up the convergence process of BP network is described in thepresent popor.The basic idea of the approach is to nonlinearize the synaptic weights of the network.Thesigmoid fu ncti on as well as the Chebyshev polynomiols are both taken as the nonlinear weights to conductthe comparison between the linear and nonlinear weighted algorithms. Simulation results show that theweight-nonlineariZation has paved a new way to further improve the convergence speed of the BP network. |
