Query: A Survey of Fairness-Aware Federated Learning   Recent advances in Federated Learning (FL) have brought large-scale machine
learning opportunities for massive distributed clients with performance and
data privacy guarantees. However, most current works only focus on the interest
of the central controller in FL, and ignore the interests of clients. This may
result in unfairness which discourages clients from actively participating in
the learning process and damages the sustainability of the whole FL system.
Therefore, the topic of ensuring fairness in an FL is attracting a great deal
of research interest. In recent years, diverse Fairness-Aware FL (FAFL)
approaches have been proposed in an effort to achieve fairness in FL from
different viewpoints. However, there is no comprehensive survey which helps
readers gain insight into this interdisciplinary field. This paper aims to
provide such a survey. By examining the fundamental and simplifying
assumptions, as well as the notions of fairness adopted by existing literature
in this field, we propose a taxonomy of FAFL approaches covering major steps in
FL, including client selection, optimization, contribution evaluation and
incentive distribution. In addition, we discuss the main metrics for
experimentally evaluating the performance of FAFL approaches, and suggest some
promising future research directions.
