Understand

In recent years, post-hoc local instance-level and global dataset-level explainability of black-box models has received a lot of attention.

  • Much less attention has been given to obtaining insights at intermediate or group levels, which is a need outlined in recent works that study the challenges in realizing the guidelines in the General Data Protection Regulation (GDPR).
  • In this paper, we propose a meta-method that, given a typical local explainability method, can build a multilevel explanation tree.
  • The leaves of this tree correspond to the local explanations, the root corresponds to the global explanation, and intermediate levels correspond to explanations for groups of data points that it automatically clusters.
