K means clustering advantages

WebApr 5, 2024 · DBSCAN has several advantages over other clustering algorithms: It does not require specifying the number of clusters beforehand. It can handle clusters of arbitrary shape and size. The slow "standard algorithm" for k-means clustering, and its associated expectation-maximization algorithm, is a special case of a Gaussian mixture model, specifically, the limiting case when fixing all covariances to be diagonal, equal and have infinitesimal small variance. Instead of small variances, a hard cluster assignment can also be used to show another equivalence of k-means clustering to a special case of "hard" Gaussian mixture modelling. This d…
