WebMar 11, 2024 · K-Means clustering is one of the unsupervised learning methods that are sensitive to outliers. K-Medoids clustering solves this problem by changing a simple yet critical aspect of K-Means. Open in app WebK-means algorithm to use. The classical EM-style algorithm is "lloyd" . The "elkan" variation can be more efficient on some datasets with well-defined clusters, by using the triangle inequality. However it’s more memory intensive due to the allocation of an extra array of shape (n_samples, n_clusters).
