Returns a nested list of <code><a href="/link/FeatSelResult?package=mlr&version=2.7" rd-options="" data-mini-rdoc="mlr::FeatSelResult">FeatSelResult</a></code>s. The first level of nesting is by data set, the second by learner, the third for the benchmark resampling iterations. If <code>as.df</code> is <code>TRUE</code>, a data frame with <dquote>task.id</dquote>, <dquote>learner.id</dquote>, the resample iteration and the selected features is returned.<p></p><p>Note that if more than one feature is selected and a data frame is requested, there will be multiple rows for the same dataset-learner-iteration; one for each selected feature.</p>

getBMRFeatSelResults

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.

getBMRFeatSelResults: Extract the feature selection results from a benchmark result.
