Detailed Description

A model of the concept Neighbor Weighting Method to be used with KNN to weight the votes of the k nearest neighbors of a sample.

KNN_ReciprocalRank weights the vote of a nearest neighbor with its reciprocal rank. The class of the nearest neighbor gets the vote 1/1, the class of the second nearest neighbor gets the vote 1/2, and so on

void theplu::yat::classifier::KNN_ReciprocalRank::operator() ( const utility::VectorBase distance,
const std::vector< size_t > &  k_sorted,
const Target target,
utility::VectorMutable prediction 
) const

The total vote for each class is calculated and returned in prediction.
