Density-based clusteringNearest neighbor graphDBSCANDensity-based clustering has several desirable properties, such as the abilities to handle and identify noise samples, discover clusters of arbitrary shapes, and automatically discover of the number of clusters. Identifying the core samples within the ...
This chapter describes DBSCAN, a density-based clustering algorithm, introduced in Ester et al. 1996, which can be used to identify clusters of any shape in data set containing noise and outliers. DBSCAN stands for Density-Based Spatial Clustering and Application with Noise. The advantages of DBS...
DBSCAN(Density-Based Spatial Clustering and Application with Noise), is adensity-based cluseringalgorithm(Ester et al. 1996), which can be used to identify clusters of any shape in a data set containing noise and outliers. The basic idea behind the density-based clustering approach is derived ...

Density-based clustering is the task of discovering high-density regions of entities (clusters) that are separated from each other by contiguous regions of low-density. DBSCAN is, arguably, the most popular density-based clustering algorithm. However, it
