A Hybrid-Order Distributed SGD Method for Non-Convex Optimization to Balance Communication Overhead, Computational Complexity, and Convergence Rate
Naeimeh Omidvar, Mohammad Ali Maddah-Ali, Hamed Mahdavi
In this paper, we propose a method of distributed stochastic gradient descent (SGD), with low communication load and computational complexity, and still fast convergence. To reduce…
Parallel Stochastic Optimization Framework for Large-Scale Non-Convex Stochastic Problems
Naeimeh Omidvar, An Liu, Vincent Lau +2
In this paper, we consider the problem of stochastic optimization, where the objective function is in terms of the expectation of a (possibly non-convex) cost function that is para…
Efficient, Fair and QoS-Aware Policies for Wirelessly Powered Communication Networks
Roohollah Rezaei, Naeimeh Omidvar, Mohammad Movahednasab +3
Wireless power transfer (WPT) is a viable source of energy for wirelessly powered communication networks (WPCNs). In this paper, we first consider WPT from an energy access point (…
An Energy-Efficient Controller for Wirelessly-Powered Communication Networks
Mohammad Movahednasab, Behrooz Makki, Naeimeh Omidvar +3
In a wirelessly-powered communication network (WPCN), an energy access point (E-AP) supplies the energy needs of the network nodes through radio frequency wave transmission, and th…
Joint Data Routing and Power Scheduling for Wireless Powered Communication Networks
Mohammad Movahednasab, Naeimeh Omidvar, Mohammad Reza Pakravan +1
In a wireless powered communication network (WPCN), an energy access point supplies the energy needs of the network nodes through radio frequency wave transmission, and the nodes s…
Optimal and Near-Optimal Policies for Wireless Power Transfer in Energy-Limited and Power-Limited Scenarios
Roohollah Rezaei, Mohammad Movahednasab, Naeimeh Omidvar +1
Radio frequency wireless power transfer (RF-WPT) is an emerging technology that enables transferring energy from an energy access point (E-AP) to multiple energy receivers (E-Rs),…
