WebJul 27, 2024 · 2. Just in case you don't know: Kmeans is a centroid-based method (each cluster is just a centroid and all points belong to the nearest centroid). DBSCAN is density-based, so the resulting clusters can have any shape, as long as there are points close enough to each other. So DBSCAN could also result in a "ball"-cluster in the center with … WebJun 2, 2024 · Using the factoextra R package.
