Abstract

The paper deals with a design of a suitable neural network structure to approximate a nonlinear function of the identified system. Contrary to the recent algorithms, the proposed structure adaptation algorithm can be applied on-line during the identification process. The designed algorithm consist of a statistical test for making decision about suitability of an a priori chosen network and then either a growing or a pruning according to the size of the network is applied. The acceptance or rejection of the model is realized by application of the statistical cumulative sum test from the decision making field. The growing part of the algorithm repeatedly utilizes principle of the learning methodology for detecting faults in nonlinear dynamical systems for adding neurons to the hidden layer. Finally, the pruning algorithm is based on a measure of sensitivity of the model output error to the removing of the network connections
