Convergence and Equilibria Analysis of a Networked Bivirus Epidemic Model
Mengbin Ye, Brian D. O. Anderson, Ji Liu
This paper studies a networked bivirus model, in which two competing viruses spread across a network of interconnected populations; each node represents a population with a large n…
Decentralized Upper Confidence Bound Algorithms for Homogeneous Multi-Agent Multi-Armed Bandits
Jingxuan Zhu, Ethan Mulle, Christopher S. Smith +2
This paper studies a decentralized homogeneous multi-armed bandit problem in a multi-agent network. The problem is simultaneously solved by agents assuming they face a common s…
PASTO: Strategic Parameter Optimization in Recommendation Systems -- Probabilistic is Better than Deterministic
Weicong Ding, Hanlin Tang, Jingshuo Feng +17
Real-world recommendation systems often consist of two phases. In the first phase, multiple predictive models produce the probability of different immediate user actions. In the se…
Reputation and Pricing Dynamics in Online Markets
Qian Ma, Jianwei Huang, Tamer Başar +2
We study the economic interactions among sellers and buyers in online markets. In such markets, buyers have limited information about the product quality, but can observe the selle…
On a Network SIS Epidemic Model with Cooperative and Antagonistic Opinion Dynamics
Baike She, Ji Liu, Shreyas Sundaram +1
We propose a mathematical model to study coupled epidemic and opinion dynamics in a network of communities. Our model captures SIS epidemic dynamics whose evolution is dependent on…
Gossip over Holonomic Graphs
Xudong Chen, Mohamed-Ali Belabbas, Ji Liu
A gossip process is an iterative process in a multi-agent system where only two neighboring agents communicate at each iteration and update their states. The neighboring condition…
