preprint Fairness through regularization for learning to rank draft Nikola H Konstantinov author 4B9D76E4-F248-11E8-B48F-1D18A9856A870009-0009-5204-7621 Christoph Lampert author 40C20FD2-F248-11E8-B48F-1D18A9856A870000-0002-4561-241X ChLa department Given the abundance of applications of ranking in recent years, addressing fairness concerns around automated ranking systems becomes necessary for increasing the trust among end-users. Previous work on fair ranking has mostly focused on application-specific fairness notions, often tailored to online advertising, and it rarely considers learning as part of the process. In this work, we show how to transfer numerous fairness notions from binary classification to a learning to rank setting. Our formalism allows us to design methods for incorporating fairness objectives with provable generalization guarantees. An extensive experimental evaluation shows that our method can improve ranking fairness substantially with no or only little loss of model quality. 2021 eng arXiv 2102.0599610.48550/arXiv.2102.05996 https://research-explorer.ista.ac.at/record/10799 Konstantinov, Nikola H, and Christoph Lampert. “Fairness through Regularization for Learning to Rank.” ArXiv, n.d. <a href="https://doi.org/10.48550/arXiv.2102.05996">https://doi.org/10.48550/arXiv.2102.05996</a>.
