Data-driven advice for interpreting local and global model predictions in bioinformatics problems

no code implementations13 Aug 2021 Markus Loecher, Qi Wu

For random forests, we find extremely high similarities and correlations of both local and global SHAP values and CFC scores, leading to very similar rankings and interpretations.

From unbiased MDI Feature Importance to Explainable AI for Trees

no code implementations26 Mar 2020 Markus Loecher

We attempt to give a unifying view of the various recent attempts to (i) improve the interpretability of tree-based models and (ii) debias the the default variable-importance measure in random Forests, Gini importance.

no code implementations4 Mar 2020 Markus Loecher

The default variable-importance measure in random Forests, Gini importance, has been shown to suffer from the bias of the underlying Gini-gain splitting criterion.
