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 from single-linkage clustering and OPTICS, eliminating the parameter and offering performance improvements over OPTICS. WebApr 28, 2011 · The OPTICS implementation in Weka is essentially unmaintained and just as incomplete. It doesn't actually produce clusters, it only computes the cluster order. For …

WebOPTICS algorithm. Ordering points to identify the clustering structure ( OPTICS) is an algorithm for finding density-based [1] clusters in spatial data. It was presented by Mihael Ankerst, Markus M. Breunig, Hans-Peter Kriegel and Jörg Sander. [2] Its basic idea is similar to DBSCAN, [3] but it addresses one of DBSCAN's major weaknesses: the ...
