Abstract:It is closely related between the performance of clustering algorithms and the structure of data sets. No methods were good enough for all types of data, nor were all methods equally applicable to all problems, and were short of reasonable interpretation to data structure. And systematic researched the clustering tendency, which was one of key problem about clustering analysis. This paper discussed it based on statistic tests, visual analysis and so on, and proved that it could present reasonable and effective analysis tools for unsupervised clustering analysis of data sets. ......
