They used DBSCAN to cluster commonly asked queries and Guangchun Luo, et.al, proposed system of cluster analysis occupies a pivotal position in data mining, and the DBSCAN algorithm is a standout amongst the most broadly utilized algorithms for clustering. Nonetheless, when the existing parallel...
There are a lot of clusters that DBSCAN can discover which are unable to find by using KMeans clustering algorithm. But, DBSCAN does not work well when we deal with clusters of varying densities and high dimensional data. It is sensitive to clustering parameters like MinPts and Eps values. ...

利用遗传思想进行数据划分的DBSCAN算法研究
An Improved Adaptive and Fast AF-DBSCAN Clustering Algorithm 摘要:针对基于密度的DBSCAN聚类算法及其改进算法在全局参数Eps与MinPts选择上需人工干预以及区域查询方式过程复杂和查询易丢失对象等不足,提出一种改进的参数自适应以及区域快速查询的密度聚类算法。根据KNN分布与数学统计分析自适应计算出最优全局参数Eps与MinPt...
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...
Finally , an incremental processing method was applied to determine t he influence on clustering of inserting or deleting data objects. The results show that an implementation of the new met hod solves existing problems treated by the DBSCAN algorithm : Both the efficiencyand the cluster quality ...
