| Abstract: | To remedy the weaknesses of back propagation(BP) neural network model and its learning algorithm,a weights-direct-determination and structure-adaptive-determination method of feed-forward neural network activated with the 2nd -class Chebyshev orthogonal polynomials was developed.Theoretical analysis and simulation results both show that the proposed system can remedy the weaknesses of BP neural network model and its learning algorithm,and the calculation speed and working precision improve a lot comparing w... |
