Web2.2 Hierarchical Models. Many of the hierarchical methods assume a dissimilarity function specifying a numerical dissimilarity d ( i, j) for each pair of objects i, j. If d satisfies the ultrametric inequality for every triple i, j, k. (2) then the various hierarchical algorithms discussed in Sect. 1.2 all produce the same clusters.
