混合核函数SVM在变压器状态评估中的应用

摘要

核函数是SVM（Support Vector Machine，支持向量机）的重要组成部分，核函数的选取对分类效果有明显的影响。该文把混合核函数引入到变压器状态评估中。实例分析表明，混合核函数支持向量机提高了状态评估的准确率。%Kernel function is an important part of SVM,the selection of kernel function to classification has a significant effect.This paper put the mixed kernel function into the state assessment of transformer.By sample data,we prove that the mixed kernel function of support vector machine can increase the state assessment accuracy of transformer.
