WebApr 11, 2024 · Re-Weighted Softmax Cross-Entropy to Control Forgetting in Federated Learning. In Federated Learning, a global model is learned by aggregating model updates computed at a set of independent client nodes, to reduce communication costs multiple gradient steps are performed at each node prior to aggregation. A key challenge in this …
