摘要:

本文提出了一种新的聚类之间的距离度量,它结合了点和聚类的空间分布信息。我们的方法建立在一个基于希尔伯特空间的集群表示的组成点的表示相结合的想法。我们使用这种表示和底层的度量设计一个空间感知的共识聚类过程。这种共识过程是通过一种新的减少欧几里德聚类,是简单和有效的。我们所有的结果适用于软和硬集群。我们伴随着这些算法与详细的实验评估,证明了我们的技术的效率和质量。

英文摘要:

This paper proposes a new distance metric between clusterings that incorporates information about the spatial distribution of points and clusters. Our approach builds on the idea of a Hilbert space-based representation of clusters as a combination of the representations of their constituent points. We use this representation and the underlying metric to design a spatially-aware consensus clustering procedure. This consensus procedure is implemented via a novel reduction to Euclidean clustering, and is both simple and efficient. All of our results apply to both soft and hard clusterings. We accompany these algorithms with a detailed experimental evaluation that demonstrates the efficiency and quality of our techniques.
