IRadialBasisKernel Interface |
Namespace: Accord.Statistics.Kernels
The IRadialBasisKernel type exposes the following members.
Name | Description | |
---|---|---|
Function(Double) |
The kernel function.
| |
Function(T, T) |
The kernel function.
(Inherited from IKernelT.) |
Name | Description | |
---|---|---|
Distance |
Computes the kernel distance for a kernel function even if it doesn't
implement the IDistance interface. Can be used to check
the proper implementation of the distance function.
(Defined by Tools.) |
A radial basis function (RBF) is a real-valued function whose value depends only on the distance from the origin, so that ϕ(x) = ϕ(||x||); or alternatively on the distance from some other point c, called a center, so that ϕ(x,c) = ϕ(||x−c||). Any function ϕ that satisfies the property ϕ(x) = ϕ(||x||) is a radial function. The norm is usually Euclidean distance, although other distance functions are also possible.
Examples of radial basis kernels include:
