+an experimental extension for survival analysis, clustering and general,
+example-specific cost-sensitive learning.  Generic resampling, including
+cross-validation, bootstrapping and subsampling.  Hyperparameter tuning with
+modern optimization techniques, for single- and multi-objective problems.
+Filter and wrapper methods for feature selection.  Extension of basic learners
+with additional operations common in machine learning, also allowing for easy
+nested resampling.  Most operations can be parallelized.")
