Fairness in Link Prediction Beyond Demographic Parity: A Reproducibility Study
By Valentijn Oldenburg · Paper · cs.LG
In fair ranked link prediction, demographic parity ($Δ_\mathrm{DP}$) is a common fairness metric. Yet, Mattos et al. (2025) argue that it fails to detect exposure bias because it ignores where links appear in the ranking. In this study, we reproduce this claim by showing that $Δ_
