class RMlr(RPackage):
"""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."""
