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…
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,…
Distributed Voting/Ranking with Optimal Number of States per Node
Saber Salehkaleybar, Arsalan Sharif-Nassab, S. Jamaloddin Golestani
Considering a network with nodes, where each node initially votes for one (or more) choices out of possible choices, we present a Distributed Multi-choice Voting/Ranking (D…
