A Robust BP Learning Algorithm of Neural Networks for Nonlinear System Identification

In this paper, the problem on robust learning algorithm of the neural networks for system identification is discussed. By constructing a new dynamic robust objective function, the RBP algorithm can continually estimate the approximation accuracy, and put the good samples into the domain of intensive learning, and can effectively resist to the noise perturbation. Experiment results show that the RBP algorithm is rubust,fast and convenient in iterative computation.
