Summary
| Description |
Deutsch: DBSCAN-Clusteranalyse auf einem Datensatz mit Gauss-verteilten Clustern. Selbst mit sorgfältig gewählten Parametern minPts und ist DBSCAN nicht in der lage, alle Cluster zur gleichen Zeit korrekt zu erfassen, da die Dichte-Unterschiede der Cluster zu groß und die Trennung der Daten gering ist. OPTICS, eine DBSCAN-Erweiterung, ist überraschend gut in der Lage, diesen Datensatz zu trennen: siehe Beispiel.
Visualisiert mit ELKI. English: Cluster analysis with DBSCAN on a gaussian-distributed-based data set. Even with carefully chosen parameters minPts and , DBSCAN is unable to capture all clusters correctly at the same time, since the difference in density is too high and the separation too low.
The visualization was generated using ELKI. |
