Hierarchical clustering threshold

WebIn fact, hierarchical clustering has (roughly) four parameters: 1. the actual algorithm (divisive vs. agglomerative), 2. the distance function, 3. the linkage criterion (single-link, … WebA hierarchical clustering method generates a sequence of partitions of data objects. It proceeds successively by either merging smaller clusters into larger ones, or by splitting larger clusters. The result of the algorithm is a tree of clusters, called dendrogram (see Fig. 1), which shows how the clusters are related.By cutting the dendrogram at a desired …
