2020 arXiv   pre-print
Theoretical analysis and empirical evaluation on several datasets confirm the efficacy of our frameworks in upholding fairness and thus facilitating federated learning in the competitive settings.  ...  We propose a novel hierarchically fair federated learning (HFFL) framework. Under this framework, agents are rewarded in proportion to their pre-negotiated contribution levels.  ...  This necessitates the notion of fairness in federated learning.  ...

2021 arXiv   pre-print
In this work, we aim to provide federated learning schemes with improved fairness.  ...  Federated learning has emerged as an important distributed learning paradigm, where a server aggregates a global model from many client-trained models while having no access to the client data.  ...  In addition, if the global model is fair, and each client updates the global model from the same fair initialization, federated learning can convergence faster to a fair solution.  ...
