WebJul 21, 2024 · 10. closest, _ = pairwise_distances_argmin_min (KMeans.cluster_centers_, X) The array closest will contain the index of the point in X that is closest to each centroid. Let's say the closest gave output as array ( [0,8,5]) for the three clusters. So X [0] is the closest point in X to centroid 0, and X [8] is the closest to centroid 1 and so on.
