DIANA (Divisive ANAlysis) (Kaufman and Rousseeuw, 1990; Macnaughton - Smith et al. 1964) is a Divisive Hierarchical Clusterer. It begins with only one cluster with all data items, and divides the clusters until the desired clusters number is reached.
clusters | [R] | |
data_set | [R] | |
number_of_clusters | [R] |
Build a new clusterer, using divisive analysis (DIANA algorithm)
Create a cluster with the item with mx distance to the rest of the cluster‘s items. That item is removed from the initial cluster.
