A Synchrophasor Data-driven Method for Forced Oscillation Localization under Resonance Conditions
Tong Huang, Nikolaos M. Freris, P. R. Kumar +1
This paper proposes a data-driven algorithm of locating the source of forced oscillations and suggests the physical interpretation of the method. By leveraging the sparsity of the…
A software-defined architecture for control of IoT Cyberphysical Systems
Ala' Darabseh, Nikolaos M. Freris
Based on software-defined principles, we propose a holistic architecture for Cyberphysical Systems (CPS) and Internet of Things (IoT) applications, and highlight the merits pertain…
Sparse Travel Time Estimation from Streaming Data
Saif Eddin Jabari, Nikolaos M. Freris, Deepthi Mary Dilip
We address two shortcomings in online travel time estimation methods for congested urban traffic. The first shortcoming is related to the determination of the number of mixture mod…
Consensus over evolutionary graphs
Michalis Smyrnakis, Nikolaos M. Freris, Hamidou Tembine
We establish average consensus on graphs with dynamic topologies prescribed by evolutionary games among strategic agents. Each agent possesses a private reward function and dynamic…
SUCAG: Stochastic Unbiased Curvature-aided Gradient Method for Distributed Optimization
Hoi-To Wai, Nikolaos M. Freris, Angelia Nedic +1
We propose and analyze a new stochastic gradient method, which we call Stochastic Unbiased Curvature-aided Gradient (SUCAG), for finite sum optimization problems. SUCAG constitutes…
