First, the hidden layer parameters of the most traditional RBFNFIS antecedent part were decided in advance and the output weights of the consequent part are evaluated by least square estimation manner. The fixed hidden layer structure of the RBFNFIS is lack of flexibility and can not adjust the structure of the RBFNFIS effectively according to the dynamic behavior of the system. The use of least square estimation for output weights values, the accuracy of the weights values will be affected by the outliers of the nonlinear function and the approximation performance is reduce for RBFNFIS. This thesis uses our previous research result: Self-Constructing RBFNFIS hidden layer structure and parameter with particle swarm optimizer (PSO) and use Least Wilcoxon norm to increase the accuracy of the output weights with outliers. This thesis uses many non-linear function approximation problems to verify the proposed method. The experiments results shows proposed method not only effetely solve outliers’ problems, but also increase the calculate time. Tsung-Ying Sun 孫宗瀛 2008 學位論文 ; thesis 111 zh-TW
