基于二元B样条基的核函数及支持向量机研究

Kernel Function based on Two-variable b-spline basis and SVM

在支持向量机方法中,核函数起着关键的作用.利用2-型三角剖分上的样条函数空间(S21(Δmn))的一组二元B样条基构造了一种新的核函数,并应用到二元函数的逼近中,取得了良好的效果.

the kernel function is important in SVM method.A new kernel function with a group of two-variable b-spline basis of type-2 triangulation in S12（Δmn）is built,and the effect is shown by its applications to two-variable function approximation.
