Setwise Coordinate Descent for Dual Asynchronous Decentralized Optimization
Marina Costantini, Nikolaos Liakopoulos, Panayotis Mertikopoulos +1
In decentralized optimization over networks, synchronizing the updates of all nodes incurs significant communication overhead. For this reason, much of the recent literature has fo…
Pick your Neighbor: Local Gauss-Southwell Rule for Fast Asynchronous Decentralized Optimization
Marina Costantini, Nikolaos Liakopoulos, Panayotis Mertikopoulos +1
In decentralized optimization environments, each agent in a network of nodes has its own private function , and nodes communicate with their neighbors to cooperatively…
Optimizing Adaptive Video Streaming in Mobile Networks via Online Learning
Theodoros Karagkioules, Georgios S. Paschos, Nikolaos Liakopoulos +3
In this paper, we propose a novel algorithm for video rate adaptation in HTTP Adaptive Streaming (HAS), based on online learning. The proposed algorithm, named Learn2Adapt (L2A), i…
Computational Optimal Transport for 5G Massive C-RAN Device Association
Georgios Paschos, Nikolaos Liakopoulos, Merouane Debbah +1
The massive scale of future wireless networks will create computational bottlenecks in performance optimization. In this paper, we study the problem of connecting mobile traffic to…
Problem-Adapted Artificial Intelligence for Online Network Optimization
Spyridon Vassilaras, Luigi Vigneri, Nikolaos Liakopoulos +4
Future 5G wireless networks will rely on agile and automated network management, where the usage of diverse resources must be jointly optimized with surgical accuracy. A number of…
