基于离群点检测和自适应参数的三支DBSCAN算法
Three-ways DBSCAN algorithm based on outlier detection and adaptive parameters
摘要
Abstract
Aiming at the problems of the classical DBSCAN algorithm that it is difficult to determine the global optimal para-meters and misjudge the outliers,the algorithm firstly started from the perspective of selecting the optimal parameters,genera-ted the Eps and MinPts lists by the distribution characteristics of the data set,and then carried out the full combination opera-tion of the parameters in the two lists,and then performed the clustering of the different combinations of the parameters in or-der,so as to search for the parameter corresponding to the point of the highest accuracy rate.Finally,from the perspective of outlier,the three-branch decision-making idea was combined with the outlier detection LOF algorithm.This algorithm was compared and analysed with a variety of clustering algorithms,and the results show that this algorithm can achieve the fully au-tomated selection of the global optimal parameters as well as improve the accuracy of the clustering algorithm.关键词
