Algorithmic Recourse: from Counterfactual Explanations to Interventions

Karimi, Amir-Hossein, Schölkopf, Bernhard, Valera, Isabel

Understand

As machine learning is increasingly used to inform consequential decision-making (e.g., pre-trial bail and loan approval), it becomes important to explain how the system arrived at its decision, and also suggest actions to achieve a favorable decision.

  • Counterfactual explanations -- "how the world would have (had) to be different for a desirable outcome to occur" -- aim to satisfy these criteria.
  • Existing works have primarily focused on designing algorithms to obtain counterfactual explanations for a wide range of settings.
  • However, one of the main objectives of "explanations as a means to help a data-subject act rather than merely understand" has been overlooked.
