Enum linfa_kernel::KernelMethod
source · [−]pub enum KernelMethod<F> {
Gaussian(F),
Linear,
Polynomial(F, F),
}
Expand description
The inner product definition used by a kernel.
There are three methods available:
- Gaussian(eps):
d(x, x') = exp(-norm(x - x')/eps)
- Linear:
d(x, x') = <x, x'>
- Polynomial(constant, degree):
d(x, x') = (<x, x'> + costant)^(degree)
Variants
Gaussian(F)
Gaussian(eps): exp(-norm(x - x’)/eps)
Linear
Euclidean inner product
Polynomial(F, F)
Polynomial(constant, degree): (<x, x'> + costant)^(degree)
