WebMar 25, 2014 · Clustering is a data mining technique that groups data into meaningful subclasses, known as clusters, such that it minimizes the intra-differences and maximizes inter-differences of these subclasses. Well-known algorithms include K-means, K-medoids, BIRCH, DBSCAN, OPTICS, STING, and WaveCluster. WebOPTICS algorithm. 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. [1] Its basic idea is similar to DBSCAN, [2] but it addresses one of DBSCAN's major weaknesses: the ...
