The Compairing Analysis of Cluster Results to Involve Between Cluster Distances

本文对于有类间距离因素聚类结果的比较，提出了类结构的空间描述方法和比较相似度的度量指标──夹角余弦，并推导出它的一些性质．最后，用蒙特卡洛模拟的结果阐明用夹角余弦作为聚类结果的相似性度量指标是合理的．

This paper discusses the similarity of two clustering results involving between cluster distance.Firstly, we propose the method describing clustering construction space and introduce angular separation rk as a measure of similarity. Secondly, we prove the elementary properties of rk.Finally, it is verified that the rk as a measure of similarity is reasonable by a series of Monte Carlo simulation results.
