Momentum-Buffered Local SGD for Zero-Payload Drift Correction in Federated Learning

Local SGD (FedAvg) reduces federated communication by running multiple local steps between server aggregations, but it suffers from “client drift” under non-IID data. Methods such as SCAFFOLD mitigate this drift by transmitting control variates, which roughly doubles the per-round payload. We propose Momentum-Buffered...
