I release MATLAB, R and Python codes of k-means clustering. They are very easy to use. You prepare data set, and just run the code! Then, AP clustering can be performed. Very simple and easyвЂ¦ Le partitionnement en k-moyennes (ou k-means en anglais) est une mГ©thode de partitionnement de donnГ©es et un problГЁme d'optimisation combinatoire. Г‰tant donnГ©s des points et un entier k, le problГЁme est de diviser les points en k groupes, souvent appelГ©s clusters, de faГ§on Г minimiser une certaine fonction.On considГЁre la distance d'un point Г la moyenne des points de son cluster
