Our paper “Fairness Evaluation with Item Response Theory” was accepted at WWW 2025. Congrats Ziqi!
In this paper, Fair-IRT is proposed as a novel framework applying Item Response Theory (IRT) to evaluate the fairness of predictive models by estimating their fairness ability, as well as the discrimination and difficulty of individuals. Experiments and case studies demonstrate its effectiveness in identifying unfairness using item characteristic curves (ICCs) and their flatness.
