From unbiased MDI Feature Importance to Explainable AI for Trees

Berlin School of Economics and Law(柏林经济与法律学院)

Markus Loecher

英文摘要:

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. In particular, we demonstrate a common thread among the out-of-bag based bias correction methods and their connection to local explanation for trees. In addition, we point out a bias caused by the inclusion of inbag data in the newly developed explainable AI for trees algorithms.
