WebJul 12, 2024 · SCAFFOLD: Stochastic Controlled Averaging for Federated Learning Jul 12, 2024 Speakers About Federated learning is a key scenario in modern large-scale machine learning where the data remains distributed over a large number of clients and the task is to learn a centralized model without transmitting the client data. WebAs a solution, we propose a new algorithm (SCAFFOLD) which uses control variates (variance reduction) to correct for the 'client-drift' in its local updates. We prove that …
Differential Privacy for Heterogeneous Federated Learning - GitHub
WebOct 14, 2024 · The standard optimization algorithm for federated learning is Federated Averaging (FedAvg) (mcmahan2024communication).For this algorithm, the subset of clients participating in the current round receive the global parameters x.Each client i performs a fixed (say K) steps of SGD using its local data and outputs the update Δ y iThe updates … WebThe FedAvg Baseline Algorithm. Federated Averaging (FedAvg) [1] is the first and most common algorithm used to aggregate these locally trained models at the central server at the end of each communication round. The shared global model is updated as follows: FedAvg: x(t+1;0) x(t;0) = Pm i=1 pi (t) i = Pm i=1 pi P˝ i 1 k=0 gi(x (t;k) i) (2 ... neshaminy amc 24

WebAs a solution, we propose a new algorithm (SCAFFOLD) which uses control variates (variance reduction) to correct for the 'client-drift' in its local updates. We prove that SCAFFOLD requires significantly fewer communication rounds and is not affected by data heterogeneity or client sampling.
