In this lesson, we'll take a look at the concept of divisive hierarchical clustering, what it is, an example of its use, and some analysis of how it works. Understanding Through Classification We seem to categorize almost everything we encounter. We want to know a person's gender, we wa...
What is an example of a hierarchical cluster? Consider a collection of four birds. Hierarchical clustering analysis may group these birds based on their type, pairing the two robins together and the two blue jays together. What are the two methods of hierarchical cluster?
Divisive clustering is a hierarchical clustering method that involves dividing every cluster into smaller subsets, starting with each object in a single cluster, until the desired number of clusters is achieved. It uses a top-down approach and splits clusters into two sub-clusters based on the an...
Specific analyses, such as those related to genome- wide association studies and multi-omics information, are often aimed at clustering sub-conditions of cancers and other diseases. Hierarchical clustering methods, which can be categorized into agglomerative and divisive, have been widely used in such...

Euclidean distance is one example of a dissimilarity measure. Contrast to similarity. Also see proximity and Euclidean distance. divisive hierarchical clustering methods. Divisive hierarchical clustering methods are top-down meth- ods for hierarchical clustering. All the data begin as a part of one ...
We present DIVCLUS-T on a small numerical and a small categorical example. DIVCLUS-T is then compared with two polythetic clustering methods: the Ward ascendant hierarchical clustering method and the k-means partitional method. The three algoritms are applied and compared on six databases of ...
