Résumé : Enhancing the interpretability of AI techniques is paramount for increasing their acceptability, especially in highly interdisciplinary fields such as remote sensing, in which scientists and practitioners with diverse backgrounds work together to monitor the Earth’s surface. In this context, counterfactual explanations are an emerging tool to characterize the behaviour of machine learning systems, by providing a post-hoc analysis of a given classification model. Focusing on the important task of land cover classification from remote sensing data, we propose a counterfactual explanation approach called CFE4SITS (CounterFac- tual Explanation for Satellite Image Time Series). One of its distinctive features over existing strategies is the lack of prior assumption on the targeted class for a given counterfactual explanation. This inherent flexibility allows for the automatic discovery of relationships between classes.
