Abstract

Process neural network (PNN) dealing with process inputs is widely used. Currently, the learning method of PNN is mainly based on base functions expansion. However, selecting base functions and their parameters is much difficult, and moreover, the corresponding learning method is time consuming due to integral with numbers of base functions. A numerical learning method (NL) for PNN was proposed in this study. It represented PNN's inputs and weights functions in numerical forms and trained the network in a numerical way so that NL avoided the selections of base functions and their parameters. Experiments showed that NL based PNN was more accurate and had lower computation complexity.
