| Abstract:In order to solve the difficulties in determining the weights and structure of the radial basis function (RBF) neural network. Based on the weights-direct-determination (WDD) method and the relationship among centers, variances, the number of hidden-layer neurons and the performance of the neural network, a pruning-while-growing-type weights-and-structure-determination (PWGT-WASD) algorithm is proposed. On the basis of the PWGT-WASD algorithm, a kind of RBF neural network classifier is constructed, and its classifying and antinoise ability is further discussed in this paper. Computer numerical experiment results substantiate that the proposed PWGT-WASD algorithm can determine the centers，the variances and the optimal weights and structure of RBF neural network quickly and effectively. The constructed RBF pattern classifier has the superiority in terms of classification and antinoise ability. |
