Abstract:Federated Learning (FL) is a machine learning paradigm that learns from data kept locally to safeguard the privacy of clients, whereas local SGD is typically employed on the clients' devices to improve communication efficiency. However, such a scheme is currently constrained by the slow and unstable convergence induced by clients' heterogeneous data. In this work, we identify three under-explored phenomena of the biased local learning that may explain these challenges caused by local updates in supervised FL. … Show more
