SvmKernelType Fields |
The SVMSvmKernelType type exposes the following members.
| Name | Description | |
|---|---|---|
| Chi2 |
Exponential Chi2 kernel, similar to the RBF kernel
| |
| Custom |
Custom svm kernel type
| |
| Inter |
Histogram intersection kernel. A fast kernel. K(xi,xj)=min(xi,xj).
| |
| Linear |
No mapping is done, linear discrimination (or regression) is done in the original feature space. It is the fastest option. d(x,y) = x y == (x,y)
| |
| Poly |
polynomial kernel: d(x,y) = (gamma*(xy)+coef0)^degree
| |
| Rbf |
Radial-basis-function kernel; a good choice in most cases: d(x,y) = exp(-gamma*|x-y|^2)
| |
| Sigmoid |
sigmoid function is used as a kernel: d(x,y) = tanh(gamma*(xy)+coef0)
