摘要:

Kleinberg介绍了三个自然的聚类属性,或公理,并表明它们不能同时满足任何聚类算法。我们提出了一个新的聚类属性,单调一致性,它避免了众所周知的问题行为的Kleinberg的一致性公理,和不可能的结果。也就是说,我们描述了一个聚类算法,莫尔斯聚类,灵感来自莫尔斯理论微分拓扑,它满足Kleinberg的原始公理与单调一致性取代。Morse聚类揭示了集合或图上的底层流结构,并返回表示关键顶点吸引盆的树的分区。我们还概括了克莱因伯格的公理化方法稀疏图,一致性的不可能的结果,单调一致性和莫尔斯聚类的可能性结果。

英文摘要:

Kleinberg introduced three natural clustering properties, or axioms, and showed they cannot be simultaneously satisfied by any clustering algorithm. We present a new clustering property, Monotonic Consistency, which avoids the well-known problematic behaviour of Kleinberg's Consistency axiom, and the impossibility result. Namely, we describe a clustering algorithm, Morse Clustering, inspired by Morse Theory in Differential Topology, which satisfies Kleinberg's original axioms with Consistency replaced by Monotonic Consistency. Morse clustering uncovers the underlying flow structure on a set or graph and returns a partition into trees representing basins of attraction of critical vertices. We also generalise Kleinberg's axiomatic approach to sparse graphs, showing an impossibility result for Consistency, and a possibility result for Monotonic Consistency and Morse clustering.
