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 49 of file linear_kernel.hpp.

template<typename VecType >

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

inlinestatic

Simple evaluation of the dot product.

This evaluation uses Armadillo's dot() function.

Template Parameters

VecType Type of vector (should be arma::vec or arma::spvec).

Parameters

a	First vector.
b	Second vector.

Definition at line 61 of file linear_kernel.hpp.

std::string mlpack::kernel::LinearKernel::ToString ( ) const

inline

Return a string representation of the kernel.
