AWhat changed
Separated client and server optimizers and treated average local model deltas as server pseudo-gradients, instantiating per-coordinate Adagrad, Adam and Yogi-style federated updates.
Scientific scope
Separated client and server optimizers and treated average local model deltas as server pseudo-gradients, instantiating per-coordinate Adagrad, Adam and Yogi-style federated updates. Inherits the underlying optimizers and FedAvg, not their reinvention. Original v1 main analysis assumes full client participation, bounded gradients/variance/heterogeneity and controlled client steps; broader participation extensions are discussed separately. Nonconvex stationarity and empirical gains do not imply unbiased global gradients, arbitrary tuning robustness or global optima.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
