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

◆ LinearKernel()

LinearKernel ( )
inline

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

Definition at line 39 of file linear_kernel.hpp.

Member Function Documentation

◆ Evaluate()

static double Evaluate ( const VecTypeA &  a,
const VecTypeB &  b 
)
inlinestatic

Simple evaluation of the dot product.

This evaluation uses Armadillo's dot() function.

Template Parameters
VecTypeAType of first vector (should be arma::vec or arma::sp_vec).
VecTypeBType of second vector (arma::vec / arma::sp_vec).
Parameters
aFirst vector.
bSecond vector.
Returns
K(a, b).

Definition at line 53 of file linear_kernel.hpp.

◆ Serialize()

void Serialize ( Archive &  ,
const unsigned  int 
)
inline

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

Definition at line 60 of file linear_kernel.hpp.
