In this survey, we delineate a comprehensive classification of the state-of-the-art fairness-aware approaches from a multifaceted perspective, i.e., model performance-oriented and capability-oriented. Moreover, we provide a framework to categorize and address various fairness concerns and associated technical aspects, examining their effectiveness in balancing equity and performance within FL frameworks. We further examine several significant evaluation metrics leveraged to measure fairness quantitatively. Finally, we explore exciting open research directions and propose prospective solutions that could drive future advancements in this important area, laying a solid foundation for researchers working toward fairness in FL.","doi":"10.24963/ijcai.2025/1177","url":"https://ijcai.org/proceedings/2025/1177","pdf":"https://ijcai.org/proceedings/2025/1177.pdf","markdown":"https://ijcai.org/proceedings/2025/1177.md","bibtex":"https://ijcai.org/proceedings/2025/bibtex/1177","volume":{"slug":"2025","title":"Proceedings of the Thirty-Fourth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2025","url":"https://ijcai.org/proceedings/2025/","year":2025,"location":"Montreal, Canada","dates":"16-22 August 2025","editors":"James Kwok","isbn":"978-1-956792-06-5","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2025"},"section":"Survey Track","track":"Survey Track","number":1177,"pages":{"first":10603,"last":10611},"keywords":["Machine Learning: ML: Federated learning","AI Ethics, Trust, Fairness: ETF: Fairness and diversity","AI Ethics, Trust, Fairness: ETF: Trustworthy AI","Machine Learning: General","Data Mining: DM: Parallel, distributed and cloud-based high performance mining"],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
