Detailed Description

The simple linear kernel (dot product).

For any two vectors $ x $ and $ y $ ,

$K(x, y) = x^T y$

This kernel has no parameters and therefore the evaluation can be static.

Constructor & Destructor Documentation

mlpack::kernel::LinearKernel::LinearKernel ( )

inline

This constructor does nothing; the linear kernel has no parameters to store.

Definition at line 39 of file linear_kernel.hpp.

template<typename VecTypeA , typename VecTypeB >

static double mlpack::kernel::LinearKernel::Evaluate	(	const VecTypeA &	a,
		const VecTypeB &	b
	)

inlinestatic

Simple evaluation of the dot product.

This evaluation uses Armadillo's dot() function.

Template Parameters

VecTypeA	Type of first vector (should be arma::vec or arma::sp_vec).
VecTypeB	Type of second vector (arma::vec / arma::sp_vec).

Parameters

a	First vector.
b	Second vector.

Definition at line 53 of file linear_kernel.hpp.

template<typename Archive >

void mlpack::kernel::LinearKernel::Serialize	(	Archive &	,
		const unsigned	int
	)

inline

Serialize the kernel (it has no members... do nothing).
