摘    要:提出一种基于扩展凝聚点和网格的快速聚类算法CECPG(c lustering using extended condensation pointand grid).在CECPG算法的基础上提出一种基于扩展凝聚点和网格的增量聚类算法ICECPG(increm entalc lustering using extended condensation point and grid).通过扩张凝聚点准确反映数据空间的几何特征,然后采用网格和密度相结合的方法,利用爬山法和连通性原理进行聚类处理,并在差分数据的指导下进行增量聚类.实验结果证明,CECPG算法的聚类效果优于模糊聚类算法FCM和C lique算法.

Abstract:A new kind of clustering algorithm called CECPG(clustering using extended condensation point and grid) is presented.Based on CECPG,an incremental clustering algorithm called ICECPG(incremental clustering using extended condensation point and grid) is presented in order to realize the real time clustering of the dynamic data.The creativities of these algorithms are the capturing of the shape of data space by extended condensation points,and then the using of grid-based and density-based clustering methods based on the theories of climbing hill algorithm and connectedness to cluster the data,guided by the difference data to implement incremental cluster.Experimental results confirm that the executing efficiency of CECPG is much better than Fuzzy c-Means algorithm and Clique algorithm.
Keywords:clustering  incremental clustering  extended condensation point  climbing hill algorithm  grid
