K Nearest Neighbors (KNN)

Page created in the context of the course ECE662.

K nearest neighbor (KNN) 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.
