cluster_optics_dbscan
(*, reachability, core_distances, ordering, eps)[source]¶ Performs DBSCAN extraction for an arbitrary epsilon.
Extracting the clusters runs in linear time. Note that this results in
labels_
which are close to aDBSCAN
with similar settings andeps
, only ifeps
is 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
eps
parameter. Must be set to <max_eps
. Results will be close to DBSCAN algorithm ifeps
andmax_eps
are close to one another.
- Returns
- labels_array of shape (n_samples,)
The estimated labels.
