Variable-Impact-based Feature Selection #2990

Issue migrated from trac ticket # 2990

milestone: HeuristicLab 3.3.17 | component: Algorithms.DataAnalysis | priority: medium

Using the variable impacts for iterative feature selection can currently only be done manually. Having an automatic way would be nice.

General workflow of this Variable-Impact-based Feature Selection:

  1. Train Model
  2. Calculate Variable Impacts
  3. Remove Features with low impact
  4. Repeat until model accuracy drops too much
