Online Distributed Learning Over Networks in RKH Spaces Using Random Fourier Features
Pantelis Bouboulis, Symeon Chouvardas, Sergios Theodoridis
We present a novel diffusion scheme for online kernel-based learning over networks. So far, a major drawback of any online learning algorithm, operating in a reproducing kernel Hil…
Low Complexity Channel Estimation for Millimeter Wave Systems with Hybrid A/D Antenna Processing
George C. Alexandropoulos, Symeon Chouvardas
The availability of large bandwidth at millimeter wave (mmWave) frequencies is one of the major factors that rendered very high frequencies a promising candidate enabler for fifth…
Robust On-line Matrix Completion on Graphs
Symeon Chouvardas, Mohammed Amin Abdullah, Lucas Claude +1
We study online robust matrix completion on graphs. At each iteration a vector with some entries missing is revealed and our goal is to reconstruct it by identifying the underlying…
A Diffusion Kernel LMS algorithm for nonlinear adaptive networks
Symeon Chouvardas, Moez Draief
This work presents a distributed algorithm for nonlinear adaptive learning. In particular, a set of nodes obtain measurements, sequentially one per time step, which are related via…
Online and Global Network Optimization: Towards the Next-Generation of Routing Platforms
Jérémie Leguay, Moez Draief, Symeon Chouvardas +4
The computation power of SDN controllers fosters the development of a new generation of control plane that uses compute-intensive operations to automate and optimize the network co…
Placing Dynamic Content in Caches with Small Population
Mathieu Leconte, Georgios Paschos, Lazaros Gkatzikis +3
This paper addresses a fundamental limitation for the adoption of caching for wireless access networks due to small population sizes. This shortcoming is due to two main challenges…
