sklearn.cluster.cluster_optics_dbscan¶
- sklearn.cluster.cluster_optics_dbscan(*, reachability, core_distances, ordering, eps)[source]¶
Perform DBSCAN extraction for an arbitrary epsilon.
Extracting the clusters runs in linear time. Note that this results in
labels_which are close to aDBSCANwith similar settings andeps, only ifepsis close tomax_eps.- Parameters:
- reachabilityarray of shape (n_samples,)
Reachability distances calculated by OPTICS (
reachability_).- core_distancesarray of shape (n_samples,)
Distances at which points become core (
core_distances_).- orderingarray of shape (n_samples,)
OPTICS ordered point indices (
ordering_).- epsfloat
DBSCAN
epsparameter. Must be set to <max_eps. Results will be close to DBSCAN algorithm ifepsandmax_epsare close to one another.
- Returns:
- labels_array of shape (n_samples,)
The estimated labels.
