mlr_learners_clust.mclust: Gaussian Mixture Models-Based Clustering Learner

In mlr3cluster: Cluster Extension for 'mlr3'

Gaussian Mixture Models-Based Clustering Learner

Description

A LearnerClust for model-based clustering implemented in mclust::Mclust(). The predict method uses mclust::predict.Mclust() to compute the cluster memberships for new data.

Dictionary

This Learner can be instantiated via the dictionary mlr_learners or with the associated sugar function lrn():

mlr_learners$get("clust.mclust")
lrn("clust.mclust")
