Abstract: This article proposes an optimized choice radial basis function neural network data central algorithm.This algorithm unifies the Kohonen network’s pattern classification ability，classifies firstly the result to make RBFNN the initial data center，and then uses the OLS algorithm to carry on optimized choice.The contrast simulation experiments indicate that this algorithm produces better RBFNN performance than using OLS algorithm independently.
