After Maroune’s presentation this week-end, Agathe was presenting twice at IJCAI 2025. Early this week, it was the Doctoral Consortium, and yesterday, our joint paper on “Optimal Transport on Categorical Data for Counterfactuals using Compositional Data and Dirichlet Transport” Recently, optimal transport-based approaches have gained attention for deriving counterfactuals, e.g., to quantify algorithmic discrimination. However, in the general multivariate setting, these methods are often opaque and difficult to interpret. To address this, alternative methodologies have been …
