CovFedAvg enhances federated learning model selection without calibration data

Researchers have introduced CovFedAvg, a novel method for federated model selection that aims to improve model compatibility across clients with differing data distributions. Unlike traditional FedAvg, CovFedAvg retains local models and uses curve controls to guide the aggregation process towards a shared endpoint. This approach does not require centralized calibration data or client-to-client sample exchange, and it guarantees that the selected model's training loss does not exceed that of the previous round's FedAvg candidate. While experiments show modest gains in accuracy over FedAvg on synthetic and real-world datasets, the study suggests that a curve-specific advantage over equally costly optimization methods is not yet established.
