"""Machine Learning in R.
Interface to a large number of classification and regression techniques,
including machine-readable parameter descriptions. There is also 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."""
