OnConvergenceofFedProx: LocalDissimilarity InvariantBounds, Non-smoothnessandBeyond

Neural Information Processing Systems

Several popularly used FL algorithms for this setting includeFedAvg (McMahan et al., 2017), FedProx(Lietal.,2020b), We analyze its convergence behavior, expose problems, andpropose alternativesmore suitable forscaling upandgeneralization.



Calibration and Consistency of Adversarial Surrogate Losses

Neural Information Processing Systems

Adversarial robustness is an increasingly critical property of classifiers in applications. The design of robust algorithms relies on surrogate losses since the optimization of the adversarial loss with most hypothesis sets is NP-hard.
