Abstract: To predict the future total amount of the governmental preparation, an improved algorithm of RBF network was brought up by introducing GCV criterion to optimize the width parameter 〖WTBX〗σ〖WTBZ〗 and by dividing the RBF network into sub-network to optimize the performance of the network. The experimental results showed that the RBF network model based on the improved RBF network algorithm can provide smaller errors and better results than the traditional methods of total account of staffing prediction in practice, and the prediction accuracy was higher.
