Design and evaluation of explanation user interfaces for complex machine-learning systems

This thesis is set in the field of human-centered eXplicable AI (XAI), and more specifically on the intelligibility of explanations for non-expert users. The technical context is as follows: on the one hand, an opaque classifier or regressor provides a prediction, and a post-hoc XAI approach generates information that acts as explanations; on the other hand, the user receives both the prediction and these explanations. In this context, there are several issues that can limit the quality of explanations. Those we focus on are: the lack of contextual information in explanations, the lack of guidance for designing features to allow the user to explore the explanatory interface and the potential confusion that can be generated by the amount of information.
We develop an experimental procedure for designing explanation user interfaces (XUIs) and evaluating their intelligibility with non-expert users. We propose several generic XAI principles and their implementation in different XUIs for explanations expressed as feature importance scores and counterfactual examples. We evaluate the objective understanding and satisfaction of these interfaces through user studies. At a fundamental level, we consider the theoretical question of possible inconsistencies in these explanations. We study these inconsistencies and propose a typology to structure the most common inconsistencies in the literature.
