WebTo understand agglomerative clustering & divisive clustering, we need to understand concepts of single linkage and complete linkage. Single linkage helps in deciding the similarity between 2 clusters which can then be merged into one cluster. Complete linkage helps with divisive clustering which is based on dissimilarity measures between clusters.
The basic principle of divisive clustering was published as the DIANA (DIvisive ANAlysis Clustering) algorithm. Initially, all data is in the same cluster, and the largest cluster is split until every object is separate. Because there exist ways of splitting each cluster, heuristics are needed. DIANA chooses the object with the maximum average dissimilarity and then moves all objects to this cluster that are more similar to the new cluster than to the remainder. how to steam library shareWebNational Center for Biotechnology Information how to steam linkWebDivisive Clustering.
