In contrast ... WebHDBSCAN - Hierarchical Density-Based Spatial Clustering of Applications with Noise. Performs DBSCAN over varying epsilon values and integrates the result to find a clustering that gives the best stability over epsilon. This allows HDBSCAN to find clusters of varying densities (unlike DBSCAN), and be more robust to parameter selection. WebDBSCAN is a density-based clustering algorithm used to identify clusters of varying shape and size with in a data set (Ester et al. 1996).
