mlpack::kernel::KernelTraits
This is a template class that can provide information about various kernels.
Definition: kernel_traits.hpp:27

mlpack
Linear algebra utility functions, generally performed on matrices or vectors.
Definition: cv.hpp:1

mlpack::kernel::CosineDistance
The cosine distance (or cosine similarity).
Definition: cosine_distance.hpp:31

cosine_distance_impl.hpp

mlpack::kernel::CosineDistance::serialize
void serialize(Archive &, const uint32_t)
Serialize the class (there&#39;s nothing to save).
Definition: cosine_distance.hpp:46

prereqs.hpp
The core includes that mlpack expects; standard C++ includes and Armadillo.

mlpack::kernel::CosineDistance::Evaluate
static double Evaluate(const VecTypeA &a, const VecTypeB &b)
Computes the cosine distance between two points.
