凸聚类的统计性质

Statistical Properties of Convex Clustering

Kean Ming Tan, Daniela Witten

摘要:

本文研究了凸聚类的统计性质。我们建立了凸聚类是密切相关的单链接层次聚类和$k$ -均值聚类。此外,我们推导出的凸聚类,产生一个非平凡的解决方案的调整参数的范围。我们还提供了一个无偏估计的自由度,并提供了一个有限的样本约束的凸聚类的预测误差。我们比较了凸聚类和一些传统的聚类方法在模拟研究。

英文摘要:

In this manuscript, we study the statistical properties of convex clustering. We establish that convex clustering is closely related to single linkage hierarchical clustering and $k$-means clustering. In addition, we derive the range of tuning parameter for convex clustering that yields a non-trivial solution. We also provide an unbiased estimate of the degrees of freedom, and provide a finite sample bound for the prediction error for convex clustering. We compare convex clustering to some traditional clustering methods in simulation studies.
