On the Impact of Gaslighting on Partially Observed Stochastic Control
Shutian Liu, Quanyan Zhu
Recent years have witnessed a significant increase in cyber crimes and system failures caused by misinformation. Many of these instances can be classified as gaslighting, which inv…
The Inverse Problem of Linear-Quadratic Differential Games: When is a Control Strategies Profile Nash?
Yunhan Huang, Tao Zhang, Quanyan Zhu
This paper aims to formulate and study the inverse problem of non-cooperative linear quadratic games: Given a profile of control strategies, find cost parameters for which this pro…
Stackelberg Risk Preference Design
Shutian Liu, Quanyan Zhu
Risk measures are commonly used to capture the risk preferences of decision-makers (DMs). The decisions of DMs can be nudged or manipulated when their risk preferences are influenc…
Optimal Control of Joint Multi-Virus Infection and Information Spreading
Vladislav Taynitskiy, Elena Gubar, Denis Fedyanin +2
Nowadays, epidemic models provide an appropriate tool for describing the propagation of biological viruses in human or animal populations, or rumours and other kinds of information…
Continuous-Time Markov Decision Processes with Controlled Observations
Yunhan Huang, Veeraruna Kavitha, Quanyan Zhu
In this paper, we study a continuous-time discounted jump Markov decision process with both controlled actions and observations. The observation is only available for a discrete se…
A Differential Game Approach to Decentralized Virus-Resistant Weight Adaptation Policy over Complex Networks
Yunhan Huang, Quanyan Zhu
Increasing connectivity of communication networks enables large-scale distributed processing over networks and improves the efficiency for information exchange. However, malware an…
Consensus-based Distributed Discrete Optimal Transport for Decentralized Resource Matching
Rui Zhang, Quanyan Zhu
Optimal transport has been used extensively in resource matching to promote the efficiency of resources usages by matching sources to targets. However, it requires a significant am…
Optimal control of diffusion processes pertaining to an opioid epidemic dynamical model with random perturbations
Getachew K. Befekadu, Quanyan Zhu
In this paper, we consider the problem of controlling a diffusion process pertaining to an opioid epidemic dynamical model with random perturbation so as to prevent it from leaving…
A further study on the opioid epidemic dynamical model with random perturbation
Getachew K. Befekadu, Quanyan Zhu
In this paper, we consider an opioid epidemic dynamical model with random perturbation that typically describes the interplay between regular prescription use, addictive use, and t…
Risk-Sensitive Mean Field Games
Hamidou Tembine, Quanyan Zhu, Tamer Basar
In this paper, we study a class of risk-sensitive mean-field stochastic differential games. We show that under appropriate regularity conditions, the mean-field value of the stocha…
