"""HDBSCAN - 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. In practice this means that HDBSCAN
|
|
returns a good clustering straight away with little or no
|
|
parameter tuning -- and the primary parameter, minimum cluster
|
|
size, is intuitive and easy to select. HDBSCAN is ideal for
|
|
exploratory data analysis; it's a fast and robust algorithm that
|
|
you can trust to return meaningful clusters (if there are any)."""
