基于SVM参数寻优的GPS高程转换模型

摘要

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.%论述支持向量机(SVM)建模参数的不同寻优思路,通过三组GPS高程转换方案,利用参数寻优时间、转换精度等指标,分析了不同参数寻优方法的特点与应用效果.
