Sequential Conditional Transport on Probabilistic Graphs for Interpretable Counterfactual Fairness
<|reference_start|>Sequential Conditional Transport on Probabilistic Graphs for Interpretable Counterfactual Fairness: In this paper, we link two existing approaches to derive counterfactuals: adaptations based on a causal graph, as suggested in Ple\v{c}ko and Meinshausen (2020) and optimal transport, as in De Lara et al. (2024). We extend "Knothe's rearrangement" Bonnotte (2013) and "triangular transport" Zech and Marzouk (2022a) to probabilistic graphical models, and use this counterfactual approach, referred to as sequential transport, to discuss individual fairness. After establishing the theoretical foundations of the proposed method, we demonstrate its application through numerical experiments on both synthetic and real datasets.<|reference_end|>
