A Class of New Discrete Time-Delay Recurrent RBF Neural Networks

A class of recurrent RBF neural networks with discrete time FIR/IIR filters are presented. The discrete time FIR/IIR filters in their output layers replace the output linear weights in general RBF neural networks in order to apply them to identification and control of discrete dynamic systems and prediction of chaotic time series. The learning algorithms are simple and can avoid unstability existing in conventional recurrent algorithms. Application of the new neural networks to modelling dynamic systems shows their superiority.
