Abstract
A simple model based on the combination of neural network and wavelet techniques named wavelet neural network (WNN) is proposed. Thanks to the time-frequency analysis feature of wavelet, a selection method that takes into account the domain of input space where the wavelets are not zero is used to initialize the translation and dilation parameters. A proper choice of initialize parameters is found to be crucial in achieving adequate training. Training algorithms for feedback WNN is discussed too. Results obtained for a nonlinear processes is presented to test the effectiveness of the proposed method. The simulation result shows that the model is capable of producing a reasonable accuracy within several steps.
