Namespaces
namespace	numerics
	Provides useful wrappers around many numerical functionality, such as dealing with sparse and dense matrix / vector data.

Typedefs
typedef std::vector< std::pair < uint32_t, float > >	numerics::sparse_vector_t

Functions
std::vector< std::pair < uint32_t, float > >	numerics::sparsify (const cv::Mat &dense)
	Converts the input 1D cv::Mat to a sparse format, where each pair in the vector is index, value. More...

float	numerics::cos_sim (const std::vector< std::pair< uint32_t, float > > &weights0, const std::vector< std::pair< uint32_t, float > > &weights1, const std::vector< float > &idfw)
	Converts the cosine similarity between two sparse weight vectors, which are premultiplied by the relevant entries in idfw. More...

float	numerics::min_hist (const std::vector< std::pair< uint32_t, float > > &weights0, const std::vector< std::pair< uint32_t, float > > &weights1, const std::vector< float > &idfw)
	Converts the histogram intersection (min) between two sparse weight vectors, which are premultiplied by the relevant entries in idfw. More...
