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 partitioning of the data space into Voronoi cells. k-means clustering minimizes within-cluster variances (squared Euclidean distances), but not regular Euclidean distances, which would be t… WebThe classic k-means clustering algorithm performs two basic steps: An assignment step in which data points are assigned to their nearest cluster centroid. An update step in which each cluster centroid is recomputed as the average of data points belonging to the cluster. The algorithm runs these two steps iteratively until a convergence ...

WebThe first step (and certainly not a trivial one) when using k-means cluster analysis is to specify the number of clusters (k) that will be formed in the final solution.
