Abstract

Federated Learning (FL) has emerged as a prominent solution for distributed learning environments, enabling collaborative model training without centralized data collection. However, FL faces significant challenges such as data heterogeneity and resource-constraint edge devices for model training and analysis, leading to accuracy degradation and bias in model performance. To address these critical issues, we propose a novel FL strategy named FedTune-SGM, designed to optimize model training in decentralized settings. In this strategy, a cloud-based model is initially trained and fine-tuned on the edge devices with additional layers tailored to the specific data characteristics. This fine-tuning process effectively mitigates the impact of data heterogeneity, enhancing the robustness and generalization capability of the model. FedTune-SGM employs a strategic weighting mechanism that ensures a balanced and equitable contribution from participating edge devices to prevent dominant influences from resource-rich devices and promote a fairer and more accurate aggregated model. Additionally, the proposed strategy integrates a Stackelberg Game model to foster an interactive and dynamic cloud-edge setup that motivates edge devices to invest more effort in model training and ensures the effectiveness of resource-constraint edge devices. Extensive experiments conducted on three diverse datasets highlight the superior performance of the proposed FedTune-SGM strategy compared to state-of-the-art FL techniques in terms of accuracy and robustness while meeting the critical challenges of data heterogeneity and resource limitations in FL environments. Through these innovations, FedTune-SGM paves the way for more reliable and efficient distributed learning systems, unlocking the full potential of FL in practical applications.
FedTune-SGM:基于stackelberg驱动的边缘网络个性化联邦学习策略
联邦学习(FL)已经成为分布式学习环境的重要解决方案,它支持无需集中数据收集的协作模型训练。然而,在模型训练和分析中,FL面临着数据异构和资源约束边缘设备等重大挑战,导致模型性能精度下降和偏差。为了解决这些关键问题,我们提出了一种名为FedTune-SGM的新颖FL策略,旨在优化分散设置下的模型训练。在这种策略中,基于云的模型最初在边缘设备上进行训练和微调,并根据特定的数据特征定制额外的层。这种微调过程有效地减轻了数据异构的影响,增强了模型的鲁棒性和泛化能力。FedTune-SGM采用战略加权机制,确保参与的边缘设备做出平衡和公平的贡献,以防止资源丰富设备的主导影响,并促进更公平和更准确的汇总模型。此外,所提出的策略集成了Stackelberg博弈模型,以培养交互式和动态的云边缘设置,激励边缘设备在模型训练中投入更多精力,并确保资源约束边缘设备的有效性。在三个不同的数据集上进行的大量实验表明,与最先进的FL技术相比,所提出的FedTune-SGM策略在准确性和鲁棒性方面具有优越的性能,同时满足了FL环境中数据异构和资源限制的关键挑战。通过这些创新,FedTune-SGM为更可靠和高效的分布式学习系统铺平了道路,释放了FL在实际应用中的全部潜力。
