WebFeb 11, 2024 · An extension or generalization of the DBSCAN algorithm is the OPTICS algorithm (Ordering Points To Identify the Clustering Structure). Pros: Knowledge about the number of clusters is not necessary; Also solves the anomaly detection task. Cons: Need to select and tune the density parameter (eps); Does not cope well with sparse data. Affinity ... WebOPTICS is an ordering algorithm with methods to extract a clustering from the ordering. While using similar concepts as DBSCAN, for OPTICS eps is only an upper limit for the neighborhood size used to reduce computational complexity. Note that minPts in OPTICS has a different effect then in DBSCAN.
