DBSCAN can find arbitrarily shaped clusters.
ELKI offers an implementation of DBSCAN as well as GDBSCAN and other variants.
DBSCAN has a notion of noise, and is robust to outliers.
PostGIS includes ST_ClusterDBSCAN- a 2D implementation of DBSCAN that uses R-tree index.
DBSCAN does not require one to specify the number of clusters in the data a priori, as opposed to k-means.
SPMF includes an implementation of the DBSCAN algorithm with k-d tree support for Euclidean distance only.
A DBSCAN cluster consists of at least one core point.
The paper provides the summary of WWLLN data cluster analysis nearest neighbor algorithm, DBSCAN algorithm.
DBSCAN requires just two parameters and is mostly insensitive to the ordering of the points in the database.
Clusterings obtained this way usually are hierarchical, andcannot be achieved by a single DBSCAN run.
The original DBSCAN algorithm does not require this by performing these steps for one point at a time.
Weka contains(as an optional package in latest versions)a basic implementation of DBSCAN that runs in quadratic time and linear memory.
DBSCAN can be used with any distance function as well as similarity functions or other predicates.
OPTICS can be seen as a generalization of DBSCAN that replaces the ε parameter with a maximum value that mostly affects performance.
DBSCAN is also used as part of subspace clustering algorithms like PreDeCon and SUBCLU.
Density-based spatial clustering of applications with noise(DBSCAN) is a data clustering algorithm proposed by Martin Ester, Hans-Peter Kriegel, Jörg Sander and Xiaowei Xu in 1996.
DBSCAN visits each point of the database, possibly multiple times e.g., as candidates to different clusters.
Recently, one of the original authors of DBSCAN has revisited DBSCAN and OPTICS, and published a refined version of hierarchical DBSCAN(HDBSCAN*), which no longer has the notion of border points.
DBSCAN is one of the most common clustering algorithms and also most cited in scientific literature.
OPTICS abstracts from DBSCAN by removing this parameter, at least to the extent of only having to give the maximum value.
DBSCAN is designed for use with databases that can accelerate region queries, e.g. using an R* tree.
Generalized DBSCAN(GDBSCAN) is a generalization by the same authors to arbitrary"neighborhood" and"dense" predicates.
DBSCAN requires two parameters: ε(eps) and the minimum number of points required to form a dense region minPts.
Various extensions to the DBSCAN algorithm have been proposed, including methods for parallelization, parameter estimation, and support for uncertain data.
Like DBSCAN, OPTICS processes each point once, and performs one ε{\displaystyle\varepsilon}-neighborhood query during this processing.
LOF shares some concepts with DBSCAN and OPTICS such as the concepts of"core distance" and"reachability distance", which are used for local density estimation.
DBSCAN cannot cluster data sets well with large differences in densities, since the minPts-ε combination cannot then be chosen appropriately for all clusters.
It is shown that DBSCAN algorithm is capable of processing WWLLN data with peculiarities and thus is the most appropriate algorithm for data clustering.
HDBSCAN is a hierarchical version of DBSCAN which is also faster than OPTICS, from which a flat partition consisting of the most prominent clusters can be extracted from the hierarchy.
Like DBSCAN, OPTICS requires two parameters: ε, which describes the maximum distance(radius) to consider, and MinPts, describing the number of points required to form a cluster.
