WebMay 7, 2024 · Though hierarchical clustering may be mathematically simple to understand, it is a mathematically very heavy algorithm. In any hierarchical clustering algorithm, you have to keep calculating the distances between data samples/subclusters and it increases the number of computations required. WebHierarchical clustering is a version of cluster analysis in which the clusters form a hierarchy or tree-like structure rather than a strict partition of the data items. In some cases, this type of clustering may be performed as a way of performing cluster analysis at multiple different scales simultaneously.
