Web22 de nov. de 2024 · 1. If you want to use your hierarchical chart to judge a good number of groups, then you can look at the height gap between splits, perhaps something like this. Bigger gaps might be seen as better and narrow gaps as involving almost arbitrary choices. So in this example, 5 groups has a big gap, as does 15 groups. Web该算法根据距离将对象连接起来形成簇(cluster)。. 可以通过连接各部分所需的最大距离来大致描述集群。. 在不同的距离,形成不同簇,这可以使用一个树状图来呈现。. 这也解 …
