KNN-K Nearest Neighbor OldKiwi - Rhea

The classifiers do not use any model to fit the data and only based on memory. The KNN uses neighborhood classification as the predication value of the new query. It has advantages - nonparametric architecture, simple and powerful, requires no traning time, but it also has disadvantage - memory intensive, classification and estimation are slow. Please refer to KNN tutorial website.
