Order Optimal Bounds for One-Shot Federated Learning over non-Convex Loss Functions
Arsalan Sharifnassab, Saber Salehkaleybar, S. Jamaloddin Golestani
We consider the problem of federated learning in a one-shot setting in which there are machines, each observing sample functions from an unknown distribution on non-convex…
Distributed Fair Scheduling for Information Exchange in Multi-Agent Systems
Majid Raeis, S. Jamaloddin Golestani
Information exchange is a crucial component of many real-world multi-agent systems. However, the communication between the agents involves two major challenges: the limited bandwid…
Order Optimal One-Shot Distributed Learning
Arsalan Sharifnassab, Saber Salehkaleybar, S. Jamaloddin Golestani
We consider distributed statistical optimization in one-shot setting, where there are machines each observing i.i.d. samples. Based on its observed samples, each machine th…
Nonexpansive Piecewise Constant Hybrid Systems are Conservative
Arsalan Sharifnassab, John N. Tsitsiklis, S. Jamaloddin Golestani
Consider a partition of into finitely many polyhedral regions and associated drift vectors . We study ``hybrid'' dynamical systems whose trajectories have a…
When do Trajectories have Bounded Sensitivity to Cumulative Perturbations?
Arsalan Sharifnassab, S. Jamaloddin Golestani
We investigate sensitivity to cumulative perturbations for a few dynamical system classes of practical interest. A system is said to have bounded sensitivity to cumulative perturba…
One-Shot Federated Learning: Theoretical Limits and Algorithms to Achieve Them
Saber Salehkaleybar, Arsalan Sharifnassab, S. Jamaloddin Golestani
We consider distributed statistical optimization in one-shot setting, where there are machines each observing i.i.d. samples. Based on its observed samples, each machine se…
Fluctuation Bounds for the Max-Weight Policy, with Applications to State Space Collapse
Arsalan Sharifnassab, John N. Tsitsiklis, S. Jamaloddin Golestani
We consider a multi-hop switched network operating under a Max-Weight (MW) scheduling policy, and show that the distance between the queue length process and a fluid solution remai…
Sensitivity to Cumulative Perturbations for a Class of Piecewise Constant Hybrid Systems
Arsalan Sharifnassab, John N. Tsitsiklis, Jamaloddin Golestani
We consider a class of continuous-time hybrid dynamical systems that correspond to subgradient flows of a piecewise linear and convex potential function with finitely many pieces,…
On the relaxed maximum-likelihood blind MIMO channel estimation for orthogonal space-time block codes
Kamran Kalbasi, S. Jamaloddin Golestani
This paper concerns the maximum-likelihood channel estimation for MIMO systems with orthogonal space-time block codes when the finite alphabet constraint of the signal constellatio…
