Identifying … k-means clustering is a method of vector quantization, originally from signal processing, that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster. This results in a … See more The term "k-means" was first used by James MacQueen in 1967, though the idea goes back to Hugo Steinhaus in 1956.
