K-means clustering is one of the most popular method of vector quantization, originally from signal processing. Although this method isnot density-based, it's included in the library for completeness. http://en.wikipedia.org/wiki/K-means_clustering Installation Node: npm install density-clustering...

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 ...

DBSCAN(Density-based spatial clustering of applications with noise带噪声的基于密度的空间聚类应用)与许多更新的方法相比,它具有定义明确的集群模型,称为”密度可达性“,类似于基于链接的聚类,它基于在特定距离阈值内的链接点。然而,它只连接满足密度标准的点,在原始变体中定义为该半径内其他对象的最小数量。聚类(cl...

TheDensity-based Clusteringtool works by detecting areas where points are concentrated and where they are separated by areas that are empty or sparse. Points that are not part of a cluster are labeled as noise. This tool uses unsupervised machine learning clustering algorithms which automatical...
A new density clustering method based on boundary samples verification is proposed. • The method can handle datasets with different densities and shapes. • The method only requires one integer parameter, easy to use. • Outperforms existing methods on various benchmark datasets. ...
