On Reconstructability of Quadratic Utility Functions from the Iterations in Gradient Methods
Farhad Farokhi, Iman Shames, Michael G. Rabbat +1
In this paper, we consider a scenario where an eavesdropper can read the content of messages transmitted over a network. The nodes in the network are running a gradient algorithm t…
Optimal Radio Frequency Energy Harvesting with Limited Energy Arrival Knowledge
Zhenhua Zou, Anders Gidmark, Themistoklis Charalambous +1
In this paper, we develop optimal policies for deciding when a wireless node with radio frequency (RF) energy harvesting (EH) capabilities should try and harvest ambient RF energy.…
Energy efficient D2D communications in dynamic TDD systems
Demia Della Penda, Liqun Fu, Mikael Johansson
Network-assisted device-to-device communication is a promising technology for improving the performance of proximity-based services. This paper demonstrates how the integration of…
An Asynchronous Mini-Batch Algorithm for Regularized Stochastic Optimization
Hamid Reza Feyzmahdavian, Arda Aytekin, Mikael Johansson
Mini-batch optimization has proven to be a powerful paradigm for large-scale learning. However, the state of the art parallel mini-batch algorithms assume synchronous operation or…
Convergence analysis of approximate primal solutions in dual first-order methods
Jie Lu, Mikael Johansson
Dual first-order methods are powerful techniques for large-scale convex optimization. Although an extensive research effort has been devoted to studying their convergence propertie…
On the trade-off between control performance and communication cost in event-triggered control
Burak Demirel, Vijay Gupta, Daniel E. Quevedo +1
We consider a stochastic system where the communication between the controller and the actuator is triggered by a threshold-based rule. The communication is performed across an unr…
