Webstanford-cs221.github.io WebMar 26, 2024 · KMeans is not a classifier. It is unsupervised, so you can't just use supervised logic with it. You are trying to solve a problem that does not exist: one does not use KMeans to post existing labels. Use a supervised classifier if you have labels. – Has QUIT--Anony-Mousse Mar 26, 2024 at 18:58 1

Introduction to K-Means Clustering Algorithm in Python

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.
