Provides an interface to 'OpenML.org' to list and download machine learning data and tasks. Data and tasks can be automatically converted to 'mlr3' tasks. For a more sophisticated interface which also allows uploading experiments, see the 'OpenML' package.
This package adds the mlr3::Task
"oml" and the mlr3::Resampling
mlr3::mlr_tasks and mlr3::mlr_resamplings, respectively.
For the former you may pass either a
