WebFor scikit-learn's Kmeans, the default behavior is to run the algorithm for 10 times ( n_init parameter) using the kmeans++ ( init parameter) initialization. Elbow Method for Choosing K ¶ Another "short-comings" of K-means is that we have to specify the number of clusters before running the algorithm, which we often don't know apriori.
