Description: OPTICS ("Ordering Points To Identify the Clustering Structure") is an algorithm for finding density-based clusters in spatial data. It was
presented by Mihael Ankerst, Markus M. Breunig, Hans-Peter Kriegel and Jö rg Sander[1]. Its basic idea is similar to DBSCAN,[2] but it
addresses one of DBSCAN s major weaknesses: the problem of detecting meaningful clusters in data of varying density. In order to do so, the
points of the database are (linearly) ordered such that points which are spatially closest become neighbors in the ordering. Additionally, a
special distance is stored for each point that represents the density that needs to be accepted for a cluster in order to have both points belong to
the same cluster. This is represented as a dendrogram. Platform: |

Description: DBSCAN (Density-Based Spatial Clustering of Applications with Noise) is a data clustering algorithm
proposed by Martin Ester, Hans-Peter Kriegel, Jö rg Sander and Xiaowei Xu in 1996.[1] It is a density-based
clustering algorithm because it finds a number of clusters starting from the estimated density distribution of
corresponding nodes. DBSCAN is one of the most common clustering algorithms and also most cited in
scientific literature.[2] OPTICS can be seen as a generalization of DBSCAN to multiple ranges, effectively
replacing the parameter with a maximum search radius. Platform: |
