This packages provides essential learners for mlr3, maintained by the mlr-org team. We will most likely not add new learners to this package.

Other learners live in the mlr3learners organization and are possibly maintained by people outside the mlr-org team. There is a wiki page listing all currently available custom learners. A guide on how to create custom learners is covered in the mlr3book. Feel invited to contribute a missing learner to the mlr3 ecosystem :-)
