Faster Non-Convex Federated Learning via Global and Local Momentum

Rudrajit Das, Anish Acharya, Abolfazl Hashemi +3

We propose \texttt{FedGLOMO}, a novel federated learning (FL) algorithm with an iteration complexity of $O (ε^{- 1.5})$ to converge to an $ε$ -stationary point (i.e., $\math…

Sampling and Reconstruction of Graph Signals via Weak Submodularity and Semidefinite Relaxation

Abolfazl Hashemi, Rasoul Shafipour, Haris Vikalo +1

We study the problem of sampling a bandlimited graph signal in the presence of noise, where the objective is to select a node subset of prescribed cardinality that minimizes the si…
