WebOct 20, 2024 · In the loop, we run the K-means method. We set the number of clusters to ‘i’ and initialize with ‘K-means ++’. K-means ++ is an algorithm which runs before the actual k-means and finds the best starting points for the centroids. The next item on the agenda is setting a random state.
