GClasses::GKernel Class Reference

Detailed Description

The base class for kernel functions. Classes which implement this must provide an "apply" method that applies the kernel to two vectors. Kernels may be combined together to form a more complex kernel, to which the kernel trick will still apply.

static GKernel* GClasses::GKernel::deserialize ( GDomNode *  pNode )

static

Deserializes a kernel object.

static GKernel* GClasses::GKernel::kernelComplex1 ( )

static

Returns a complex kernel made by combining several other kernels. This might be used to exercise kernel functionality or to test non-linear metrics. The caller is responsible to delete the object this returns.

protected

Helper method used by the serialize methods in child classes.

virtual const char* GClasses::GKernel::name ( ) const

pure virtual
