论文摘要
在联合学习设置中,多个客户在中央服务器协调下共同培训模型,而培训数据则保存在客户端以确保隐私。通常,在联合网络中,不同设备的数据分布不一致,并且在End设备之间有限的通信带宽既施加了统计异质性和昂贵的通信,却是对联合学习的主要挑战。本文提出了一种算法,以实现联合学习(FEDFA)的更公平和准确性。它引入了一种采用双重动量梯度的优化方案,从而加速了模型的收敛速度。提出了一种合并训练精度和训练频率的信息数量来测量权重的适当选择算法。由于对某些客户的偏好,此程序有助于解决联邦学习中不公平的问题。我们的结果表明,拟议的FedFA算法在准确性和公平性方面优于基线算法。
In the federated learning setting, multiple clients jointly train a model under the coordination of the central server, while the training data is kept on the client to ensure privacy. Normally, inconsistent distribution of data across different devices in a federated network and limited communication bandwidth between end devices impose both statistical heterogeneity and expensive communication as major challenges for federated learning. This paper proposes an algorithm to achieve more fairness and accuracy in federated learning (FedFa). It introduces an optimization scheme that employs a double momentum gradient, thereby accelerating the convergence rate of the model. An appropriate weight selection algorithm that combines the information quantity of training accuracy and training frequency to measure the weights is proposed. This procedure assists in addressing the issue of unfairness in federated learning due to preferences for certain clients. Our results show that the proposed FedFa algorithm outperforms the baseline algorithm in terms of accuracy and fairness.
