template<typename VecType > double mlpack::kernel::SphericalKernel::ConvolutionIntegral (const VecType &a, const VecType &b) [inline]¶
Obtains the convolution integral [integral K(||x-a||)K(||b-x||)dx] for the two vectors. In this case, because our simple example kernel has no internal parameters, we can declare the function static. For a more complex example which cannot be declared static, see the GaussianKernel, which stores an internal parameter. Template Parameters:VecType Type of vector (arma::vec, arma::spvec
should be expected).
Parameters:
a First vector.
b Second vector.
Returns:
the convolution integral value.
