OPTICS-OF is an outlier detection algorithm based on OPTICS. The main use is the extraction of outliers from an existing run of OPTICS at low cost compared to using a different outlier detection method. The better known version LOF is based on the same concepts. DeLi-Clu, Density-Link-Clustering combines ideas … See more Ordering points to identify the clustering structure (OPTICS) is an algorithm for finding density-based clusters in spatial data. It was presented by Mihael Ankerst, Markus M. Breunig, Hans-Peter Kriegel and Jörg Sander. Its … See more The basic approach of OPTICS is similar to DBSCAN, but instead of maintaining known, but so far unprocessed cluster members in a set, … See more Like DBSCAN, OPTICS processes each point once, and performs one $${\displaystyle \varepsilon }$$-neighborhood query during … See more Like DBSCAN, OPTICS requires two parameters: ε, which describes the maximum distance (radius) to consider, and MinPts, … See more Using a reachability-plot (a special kind of dendrogram), the hierarchical structure of the clusters can be obtained easily.
