| Interface | Description |
|---|---|
| Kernel<InputType> |
The
Kernel interface the functionality required from an object
that implements a kernel function. |
| KernelContainer<InputType> |
Defines an object that contains a Kernel.
|
| Class | Description |
|---|---|
| DefaultKernelContainer<InputType> |
The
DefaultKernelContainer class implements an object that
contains a kernel inside. |
| DefaultKernelsContainer<InputType> |
The
DefaultKernelsContainer class implements a container of kernels. |
| ExponentialKernel<InputType> |
The
ExponentialKernel class implements a kernel that applies the
exponential function to the result of another kernel. |
| KernelDistanceMetric<InputType> |
The
KernelDistanceMetric class implements a distance metric that
utilizes an underlying Kernel for computing the distance. |
| KernelUtil |
A utility class for dealing with kernels.
|
| LinearKernel |
The
LinearKernel class implements the most basic kernel: it just
does the actual inner product between two vectors. |
| NormalizedKernel<InputType> |
The
NormalizedKernel class implements an Kernel
that returns a normalized value between 0.0 and 1.0 by normalizing the
results of a given kernel. |
| PolynomialKernel |
The
PolynomialKernel class implements a kernel for two given
vectors that is the polynomial function:
(x dot y + c)^d d is the degree of the polynomial, which must be a positive integer. |
| ProductKernel<InputType> |
The
ProductKernel class implements a kernel that takes the product
of applying multiple kernels to the same pair of inputs. |
| RadialBasisKernel |
The
RadialBasisKernel implements the standard radial basis
kernel, which is:
exp( -||x - y||^2 / (2 * sigma^2) ) where sigma is the parameter that controls the bandwidth of the kernel. |
| ScalarFunctionKernel<InputType> |
The
ScalarFunctionKernel class implements a kernel that applies a
scalar function two the two inputs to the kernel and then returns their
product. |
| SigmoidKernel |
The
SigmoidKernel class implements a sigmoid kernel based on the
hyperbolic tangent. |
| SumKernel<InputType> |
The
SumKernel class implements a kernel that adds together
the result of applying multiple kernels to the same pair of inputs. |
| VectorFunctionKernel |
The
VectorFunctionKernel implements a kernel that makes use of a
vector function plus a kernel that operates on vectors. |
| WeightedKernel<InputType> |
The
WeightedKernel class implements a kernel that takes another
kernel, evaluates it, and then the result is rescaled by a given weight. |
| ZeroKernel |
The
ZeroKernel always returns zero. |
