- Title: Counterfactual Instances Explain Little
- Authors: Adam White, Artur d'Avila Garcez
- Abstract summary: It is important to be able to explain the decisions of machine learning systems.
An increasingly popular approach has been to seek to provide emphcounterfactual instance explanations.
This paper will argue that a satisfactory explanation must consist of both counterfactual instances and a causal equation.

- Abstract: In many applications, it is important to be able to explain the decisions of
machine learning systems. An increasingly popular approach has been to seek to
provide \emph{counterfactual instance explanations}. These specify close
possible worlds in which, contrary to the facts, a person receives their
desired decision from the machine learning system. This paper will draw on
literature from the philosophy of science to argue that a satisfactory
explanation must consist of both counterfactual instances and a causal equation
(or system of equations) that support the counterfactual instances. We will
show that counterfactual instances by themselves explain little. We will
further illustrate how explainable AI methods that provide both causal
equations and counterfactual instances can successfully explain machine
learning predictions.

counterfactual explanation systems try to enable a counterfactual reasoning by modifying the input image.
We present a novel approach to generate such counterfactual image explanations based on adversarial image-to-image translation techniques.
Our results show that our approach leads to significantly better results regarding mental models, explanation satisfaction, trust, emotions, and self-efficacy than two state-of-the art systems.

We explore how to move from local partial explanations to what we call complete local explanations and then to global ones.
