Abstract: Support Vector Machine(SVM) has good performance for classification,but the performance is restricted by the kernel function and its parameters.This paper discusses the problem,and uses cross validation,grid searching for optimizing the kernel function parameters.

Key words: Support Vector Machines(SVM), kernel function, classification

摘要: 支持向量机(SVM)被证实在分类领域性能良好,但其分类性能受到核函数及参数影响。讨论核函数及参数对SVM分类性能的影响,并运用交叉验证与网格搜索法进行参数优化选择,为SVM分类核函数及参数选择提供借鉴。
