| Research Abstract |
The agglomerative hierarchical clustering algorithms is a generic name of a series of talgorithms used best in the cluster analysis. It is easy to interpret because the agglomerative hierarchical clustering algorithms can classify the object by using a dissimilarity, and can show the formation situation of the clustering in the sight in the dendrogram and is used in a lot of fields. When the data is symmetric, we proposed the index that pays attention to "space distortion", "monotonicity of the combined distance", "Structured ratio for measuring the +clustering results", and the result of the cluster analysis has been evaluated multilaterally, The result is announced as Akinobu Takeuchi, Hiroshi Yadohisa and Koichi Inada "Evaluation of the classification result in the agglomerative hierarchical clustering algorithms" (the society by the project research of the Institute of Statistical Mathematics (2004)). Moreover, we investigated the crisp and fuzzy k-means clustering algorithms for multivariate functional data in association with this research.
