摘要: 针对基于密度的空间聚类及其变种提出了拓扑的概念。给出了聚类拓扑结构的定义,把簇定义为多种拓扑连通集合。此外,运用全新的拓扑思想改进典型的算法,提出了一种拓扑聚类的新算法。实例证明此算法有效。

Abstract: The purpose of this paper is to give a topological view to the spatial clustering focusing on density based clustering with its variations.Proposes the definition of cluster topology,defines clusters as various kinds of topological connected sets.More in this paper,the topological cluster forming algorithms are presented.Then reforms some typical algorithms with the new topological view.Examples are given to show the theories.
