K-means (KM) K-means (MacQueen 1967) és un algorisme iteratiu que minimitza a cada iteració la dispersió interna dels clústers. En altres paraules, el funcional a minimitzar és la suma total dels quadrats dels errors (TESS):

K-means Clustering

K-means Clustering. Given a data point v and a set of points X , define the distance from v to X d ( v, X ) as the (Euclidian) distance from v to the closest point from X . Given a set of n data points V ={v 1 …v n } and a set of k points X ,
