Web2) The k-means algorithm is performed iteratively, where the updated centroids from the previous iteration are used to assign clusters, which are then used to update the centroids, and so on. In other words, the algorithm alternates between calling assign_to_nearest and update_centroids. WebThis process repeats until a new iteration no longer re-assigns any observations to a new cluster. At this point, the algorithm is considered to have converged, and the final cluster …
