| 摘 要： | 研究流形上的聚类分析，针对基于密度的空间聚类引入了流形概念，提出1种基于流形的密度聚类算法，该方法将流形的概念与聚类相结合，可以适用于样本为复杂分布的聚类。文中通过实例证明此算法的有效性。

| Abstract: | Clustering analysis has become an important tool in knowledge engineering and business intelligence, There are rapidly growing number of clustering algorithms, however, one of the most important clustering algorithms is the density based spatial clustering, and its various variations. These algorithms are either based on the density connected chains, or weighted density, or the gravity based connected sets. They seem similar in concept but there does not exist a unified presentation. The purpose of this paper is to give a densitybased spatial clustering on manifold, We propose a new concept on manifold clustering, which can be applied to clustering complex data in space. Examples are given to show the theories. |
