层次聚类(hierarchical clustering)可在不同层次上对数据集进行划分,形成树状的聚类结构。AggregativeClustering是一种常用的层次聚类算法。 其原理是:最初将每个对象看成一个簇,然后将这些簇根据某种规则被一步步合并,就这样不断合并直到达到预设的簇类个数。这里的关键在于:如何计算聚类簇之间的距离? ...
In this article, we discussed hierarchical clustering, which is a type of unsupervisedmachine learning algorithmthat works by grouping clusters based on distance measures and similarity. We also learned about the types of hierarchical clustering, how it works and implementing the same using Python....

Theagglomerative clusteringis the most common type of hierarchical clustering used to group objects in clusters based on their similarity. It’s also known asAGNES(Agglomerative Nesting). The algorithm starts by treating each object as a singleton cluster. Next, pairs of clusters are successively mer...
Agglomerative clusteringis the most frequent class ofhierarchical clustering, used to put items in clusters based on similarities. In this approach, each item is first treated as asingletoncluster. Following this, pairs of clusters are merged one by one until all the clusters have been combined in...
