除了需要衡量对象之间的距离之外,层次聚类算法还需要衡量cluster之间的距离,常见的cluster之间的衡量方法有 Single-link 方法、Complete-link 方法、UPGMA(Unweighted Pair Group Method using arithmetic Averages)方法、WPGMA(Weighted Pair Group Method using arithmetic Averages)方法、Centroid 方法(又称 UPGMC,Unweighte...

Divisive method分层方法 在divisive 或者从上至下的聚类方法中,所有的观测值被分配给了一个单一的聚类,然后将这个cluster分开至至少两个相似的clusters. 最后我们在每个聚类上进行递归,直到每个observation只有一个聚类。在某些情况下,分类算法比聚集算法产生的精度更高,但是从概念上更复杂。 Agglomerative method 聚集方法...

使用`average` 方法可以在等级聚类中考虑聚类之间所有成员之间的平均距离,此方法有助于捕捉到聚类的整体相似性,并在处理具有多个细分聚类的数据时可能是一个有用的选择。 6. method = "single" 当使用 `method = "single"` 进行等级聚类时,聚类间的距离是使用两个聚类中所有成员之间的最小距离来计算的。
in this order. When considering time-series datasets the scenario is more intricate. While there is no clear indication of the best method, we have empirical evidence suggesting the application of Complete-Linkage with YS1 and YR1. Regarding the use of k-medoids and Average-Linkage, Jackknife ...
