arXiv:2508.12042v3 Announce Type: replace Abstract: Federated learning (FL) allows collaborative training of machine learning models across multiple parties without sharing raw data. However, heterogeneous data can cause some clients to have disproportionate influence on the global model, leading to disparities in their performance. Fairness, understood as reducing these disparities, is therefore a crucial concern in FL and has been addressed in various ways. We studied performance equitable fairness in FL, where the goal is to minimize performance disparities across clients. We evaluated seve
The increasing adoption of federated learning in real-world applications highlights the immediate need to address fairness and performance disparities to ensure equitable outcomes as FL scales.
Ensuring fairness in federated learning addresses a critical ethical and practical challenge, preventing models from disproportionately disadvantaging certain client groups, which is crucial for broad and trusted adoption.
The focus on variance regularization introduces a new methodological approach to achieve performance-equitable fairness in federated learning, improving model reliability and societal impact across diverse datasets.
