mlr_filters_boruta: Burota Filter

In mlr3filters: Filter Based Feature Selection for 'mlr3'

Burota Filter

Description

Filter using the Boruta algorithm for feature selection. If keep = "tentative", confirmed and tentative features are returned. Note that there is no ordering in the selected features. Selected features get a score of 1, deselected features get a score of 0. The order of selected features is random. In combination with mlr3pipelines, only the filter criterion cutoff makes sense.

Initial parameter values

• num.threads:

  • Actual default: NULL, triggering auto-detection of the number of CPUs.

  • Adjusted value: 1.

  • Reason for change: Conflicting with parallelization via future.
