| 摘 要： | 目前支持向量机在模式分类中得到了很好的应用.对于线性不可分的样本空间,需要寻找核函数,将线性不可分的样本集映射到另一个高维线性空间.在理论上,怎样选择核函数,还是一个未解决的问题.因此研究支持向量机的核函数性质,对于寻找核函数有重要意义.为此,在研究支持向量机的基础上,给出了核函数的若干重要性质.

| Abstract: | At present support vector machine has found applications in model classification. As for the undivided linear sample space, the kernel function is needed to map onto another high dimension linear space. Theoretically how to choose Kernel function remains unsolved. Therefore it is of great significance to study the properties of kernel function of support vector machine. For this reason, several important properties of kernel function are discussed on the basis of support vector machine. |
