摘要

给出了一种直观地评估一组对象O = {0 /sub 1/，…的聚类倾向的方法。， 0 /下标n/}，当它们被表示为对象向量或数值两两不相似值时。对目标进行重新排序，并将重新排序的对对象不相似度矩阵显示为强度图像。集群由沿对角线的深色像素块表示。

VAT: a tool for visual assessment of (cluster) tendency

A method is given for visually assessing the cluster tendency of a set of Objects O = {o/sub 1/, . . . ,o/sub n/} when they are represented either as object vectors or by numerical pairwise dissimilarity values. The objects are reordered and the reordered matrix of pair wise object dissimilarities is displayed as an intensity image. Clusters are indicated by dark blocks of pixels along the diagonal.
