DAFL's distributed augmentation allocation lifts minority-class F1 to 0.183 and shortens convergence on CIFAR-10 federated learning

The work first links data augmentation to federated learning convergence behavior, showing that reducing label proportion imbalance accelerates convergence, and then proposes DAFL: with clients' class counts known, the server assigns the minimum augmentation per client-class pair by minimizing augmentation and training time while constraining global class imbalance; on six imbalanced configurations of CIFAR-10 with eight classes and eight clients, DAFL achieves higher minority-class F1 with shorter training time on D2, D4, D5, and D6, reaching minority-class F1 0.183±0.055 and convergence time 188.119±86.344 s on D2, outperforming FedProx and Focal Loss.
