Variable-Impact-based Feature Selection

Reported by: pfleck Owned by: pfleck
Priority: medium Milestone: HeuristicLab 3.3.17
Component: Algorithms.DataAnalysis Version: branch
Keywords: Cc:


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
