Abstract  A new algorithm is presented to improve the classification ability of the radial basis function neural network (RBFNN). It attempts to construct RBFNN based on a cooperative coevolutionary algorithm. The Kmeans method is employed and the initial hidden nodes are divided into modules to represent the species of the coevolutionary algorithms. The good individuals in all species are found and then combined to form the whole structure of RBFNN. A matrixform mixed encoding scheme with a control vector is adopted in this algorithm. The weights between the hidden layer and the output layer are calculated by pseudoinverse algorithm. The proposed algorithm is tested on UCI datasets and the results show it outperforms the other existing methods with higher accuracy and simpler network construction.
