WHERE to Generate Matters: Budget-Aware Synthetic Augmentation for Label Skewed Federated Learning
Sangwoo Lee, Sunghwan Park, Jaewoo Lee
Label skew in federated learning (FL) causes client drift and degrades global accuracy. Synthetic data augmentation can reduce this imbalance; however, full class balancing requires substantial computation cost. We propose FedEAS, a policy that assigns each client an entropy-adap…
