Noisy, Greedy and Not so Greedy k-Means++
In an optimal solution of the k-means problem, the centers are means of their clusters, and Lloyd's algorithm iterates between computing the means of all clusters as the new center set and reassigning all points to their closest centers to form new clusters.
