Webspeed up kNN classification and leads to substan-tial further improvements. 1. Introduction The k-nearest neighbors (kNN) decision rule classifies an unlabeled input by the majority label of its knearest train-ing inputs. It is one of the oldest and most intuitive classification algorithms (Cover & Hart,1967). Never- WebThe K-nearest neighbor classification rule (KNN) proposed by T. M. Cover and P. E. Hart [4], is a powerful classification method that allows an almost infallible classification of an unknown prototype through a set of training prototypes. ... In 1968 Hart [17] was the first to propose a method
