Abstract  A method of defining attribute importance is presented. In this method, the distance between samples can be measured to determine the training set clustering. The combination of two radial basis-function (RBF) neural networks for pattern recognition is proposed. The two RBF neural networks have different radial centers and they come from lower approximation and upper approximation of the clustering sets respectively. The designed rough approximation sets can solve the problem on uncertain clustering. Then, the two networks are combined under the experience risk minimum criterion. Thus, the different belief weights for outputs of neurons and the last neural networks output are determined. Finally, the simulation results of pattern recognition on UCI database show the proposed method is valid and effective.
