| Abstract: | The paper introduces a heuristic structure optimization algorithm of the radial basis probabilistic neural network(RBPNN).A moving medium centers covering hypersphere algorithm is proposed to initially select potential hidden centers vectors of the first hidden layer from all the training samples,then the genetic algorithms further prunes the structure of RBPNN,and determining the matching controlling parameters of kernel function of RBPNN.The experimental results showed that the algorithm can effectively q... |
