Divisive hierarchical clustering algorithm

Hierarchical clustering algorithms create a hierarchical decomposition of the data set using some criterion. The divisive (top-down) method splits a cluster iteratively.

  • Does the reverse of the agglomerative method by starting will all objects in the same cluster and subdividing them into smaller pieces.
  • Divisive methods are not generally available and rarely have been applied.

DIANA (Divisive Analysis)

Follows the inverse order of AGNES. Eventually each node forms a cluster on its own.
