mlr_learners_clust.agnes | R Documentation |
A LearnerClust for agglomerative hierarchical clustering implemented in cluster::agnes()
.
The predict method uses stats::cutree()
which cuts the tree resulting from
hierarchical clustering into specified number of groups (see parameter k
).
The default number for k
is 2.
This Learner can be instantiated via the dictionary mlr_learners or with the associated sugar function lrn()
:
mlr_learners$get("clust.agnes") lrn("clust.agnes")
Task type: “clust”
Predict Types: “partition”
Feature Types: “logical”, “integer”, “numeric”
Required Packages: mlr3, mlr3cluster, cluster
