We don't tell the algorithm in advance anything about the structure of the data; it discovers it on its own by figuring how to group them. HDBSCAN (Hierarchical DBSCAN) is a hybrid hierarchical and density-based technique, that similarly to OPTICS produces a dendrogram and then applies a further step to “condense” the dendrogram tree into a real set of clusters.
