Decision-Focused Learning in Network Interdiction Games
Luca M. Hartmann, Parinaz Naghizadeh
We study decision-focused learning (DFL) in shortest-path network interdiction (SPNI) games, a Stackelberg game where an interdictor (leader) strengthens the networks' arcs against…
Coordination Games on Multiplex Networks: Consensus, Convergence, and Stability of Opinion Dynamics
Ruey-An Shiu, Parinaz Naghizadeh
This paper studies opinion dynamics in multilayer networks. Extending a single-layer model, we formulate opinion updates as a synchronous coordination game in which agents minimize…
Reactive Users vs. Social Recommender Systems: Managing Opinion Drifts with Adaptive Policies
Atefeh Mollabagher, Parinaz Naghizadeh
Recommendation systems are used in a range of platforms to maximize user engagement through personalization, promotion of popular content, and the use of information from social ne…
United We Fall: On the Nash Equilibria of Multiplex and Multilayer Network Games
Raman Ebrahimi, Parinaz Naghizadeh
Network games provide a framework to study strategic decision making processes that are governed by structured interdependencies among agents. However, existing models do not accou…
Adversarial Contract Design for Private Data Commercialization
Parinaz Naghizadeh, Arunesh Sinha
The proliferation of data collection and machine learning techniques has created an opportunity for commercialization of private data by data aggregators. In this paper, we study t…
Provision of Public Goods on Networks: On Existence, Uniqueness, and Centralities
Parinaz Naghizadeh, Mingyan Liu
We consider the provision of public goods on networks of strategic agents. We study different effort outcomes of these network games, namely, the Nash equilibria, Pareto efficient…
