核函数的选择是支持向量机理论研究的一个核心问题,但是目前还没有一种针对

The choice of kernel support is a core issue of SVM theory, but at present no effective way to construct a suitable kernel for specific issues. The most commonly used kernel functions, polynomial kernel RBF kernel (radial basis function, referred RBF), Sigmoid nucleus, as shown below.

The choice of nuclear function is a core problem to support the theoretical study of vector machine, but there is no effective method to construct suitable nuclear function for specific problems. The most commonly used core functions are polynomial cores, radial base cores (RBF), Sigmoid cores, etc., as shown below.
