A LearnerClust for divisive hierarchical clustering implemented in cluster::diana()
.
The predict method uses stats::cutree()
which cuts the tree resulting from
hierarchical clustering into specified number of groups (see parameter k
).
The default value for k
is 2.
Dictionary
This Learner can be instantiated via the dictionary mlr_learners or with the associated sugar function lrn()
:
$get("clust.diana")
mlr_learnerslrn("clust.diana")
