Component
EnsembleAttributeSelectionFeature selection with multiple algorithms.
The component includes as many as possible CRAN R packages that do attribute/feature selection. Methods that have minimal parameters are included.
If a package is not installed - it is skipped. If an algorithm fails, or returns an empty set, the output is not written.
Note that due to unsolved installation problems, some of the requirements are set to manual.
