Extremum and Nash Equilibrium Seeking with Delays and PDEs: Designs & Applications
Tiago Roux Oliveira, Miroslav Krstić, Tamer Başar
The development of extremum seeking (ES) has progressed, over the past hundred years, from static maps, to finite-dimensional dynamic systems, to networks of static and dynamic age…
Structure Matters: Dynamic Policy Gradient
Sara Klein, Xiangyuan Zhang, Tamer Başar +2
In this work, we study -discounted infinite-horizon tabular Markov decision processes (MDPs) and introduce a framework called dynamic policy gradient (DynPG). The framework dire…
Revisiting Game-Theoretic Control in Socio-Technical Networks: Emerging Design Frameworks and Contemporary Applications
Quanyan Zhu, Tamer Başar
Socio-technical networks represent emerging cyber-physical infrastructures that are tightly interwoven with human networks. The coupling between human and technical networks presen…
Age of Coded Updates In Gossip Networks Under Memory and Memoryless Schemes
Erkan Bayram, Melih Bastopcu, Mohamed-Ali Belabbas +1
We consider an information update system on a gossip network, where a source node encodes information into total keys such that any subset of at least keys can fully reco…
Modeling Interfering Sources in Shared Queues for Timely Computations in Edge Computing Systems
Nail Akar, Melih Bastopcu, Sennur Ulukus +1
Most existing stochastic models on age of information (AoI) focus on a single shared server serving status update packets from sources where each packet update stream is Pois…
Semantic Communication in Multi-team Dynamic Games: A Mean Field Perspective
Shubham Aggarwal, Muhammad Aneeq uz Zaman, Melih Bastopcu +1
Coordinating communication and control is a key component in the stability and performance of networked multi-agent systems. While single user networked control systems have gained…
Best Response Strategies for Asymmetric Sensing in Linear-Quadratic Differential Games
Shubham Aggarwal, Tamer Başar, Dipankar Maity
In this paper, we revisit the two-player continuous-time infinite-horizon linear quadratic differential game problem, where one of the players can sample the state of the system on…
Robust Cooperative Multi-Agent Reinforcement Learning:A Mean-Field Type Game Perspective
Muhammad Aneeq uz Zaman, Mathieu Laurière, Alec Koppel +1
In this paper, we study the problem of robust cooperative multi-agent reinforcement learning (RL) where a large number of cooperative agents with distributed information aim to lea…
Sliding-Mode Nash Equilibrium Seeking for a Quadratic Duopoly Game
Victor Hugo Pereira Rodrigues, Tiago Roux Oliveira, Miroslav Krstić +1
This paper introduces a new method to achieve stable convergence to Nash equilibrium in duopoly noncooperative games. Inspired by the recent fixed-time Nash Equilibrium seeking (NE…
Control Theoretic Approach to Fine-Tuning and Transfer Learning
Erkan Bayram, Shenyu Liu, Mohamed-Ali Belabbas +1
Given a training set in the form of a paired , we say that the control system has learned the paired set via the control if the s…
Optimizing Profitability in Timely Gossip Networks
Priyanka Kaswan, Melih Bastopcu, Sennur Ulukus +2
We consider a communication system where a group of users, interconnected in a bidirectional gossip network, wishes to follow a time-varying source, e.g., updates on an event, in r…
How to Make Money From Fresh Data: Subscription Strategies in Age-Based Systems
Priyanka Kaswan, Melih Bastopcu, Sennur Ulukus +2
We consider a communication system consisting of a server that tracks and publishes updates about a time-varying data source or event, and a gossip network of users interested in c…
Convergence to (Coarse) Correlated Equilibria in Full-Information General-Sum Markov Games
Weichao Mao, Haoran Qiu, Chen Wang +3
No-regret learning has a long history of being closely connected to game theory. Recent works have devised uncoupled no-regret learning dynamics that, when adopted by all the playe…
