Abstract:On the basis of the theory of SVM, different parameter optimization methods of SVM modeling were discussed. Through three practical schemes of GPS height conversion, the characteristics and applied effects on SVM with the different parameter optimization methods were analyzed by the targets of optimization time and conversion accuracy.
