Behavior of Nonlinear Opinion Dynamics over Large Networks
Yu Xing, Anastasia Bizyaeva, Karl H. Johansson
Opinion dynamics have been studied for decades across disciplines, with much of the theoretical literature focusing on behaviors such as consensus, polarization, and clustering. Al…
Influence Enhancement in Opinion Dynamics Using Edge Modification: A Kron Reduction-Based Approach
Aashi Shrinate, Aravind Seshadri, Twinkle Tripathy +3
With the emergence of online social networks as a primary platform for advertising and advocacy, enhancing a user's influence has become of significant interest. In this paper, we…
Approximate Simulation-Based Verification of Compatibility of the Friedkin-Johnsen Model with Binary Observations
Yu Xing, Aneesh Raghavan, Michael T. Schaub +1
We consider a verification problem for opinion dynamics based on binary observations. The opinion dynamics is governed by a Friedkin-Johnsen (FJ) model, where only a sequence of bi…
Quantized Distributed Estimation with Event-triggered Communication and Packet Loss
Ying Wang, Yanlong Zhao, Ji-Feng Zhang +1
This paper focuses on the problem of quantized distributed estimation with event-triggered communication and packet loss, aiming to reduce the number of transmitted bits. The main…
Adding links wisely: how an influencer seeks for leadership in opinion dynamics?
Lingfei Wang, Yu Xing, Yuhao Yi +2
This paper investigates the problem of leadership development for an external influencer using the Friedkin-Johnsen (FJ) opinion dynamics model, where the influencer is modeled as…
Explainable Reinforcement Learning via Temporal Policy Decomposition
Franco Ruggeri, Alessio Russo, Rafia Inam +1
We investigate the explainability of Reinforcement Learning (RL) policies from a temporal perspective, focusing on the sequence of future outcomes associated with individual action…
Learning Communities from Equilibria of Nonlinear Opinion Dynamics
Yu Xing, Anastasia Bizyaeva, Karl H. Johansson
This paper studies community detection for a nonlinear opinion dynamics model from its equilibria. It is assumed that the underlying network is generated from a stochastic block mo…
On final opinions of the Friedkin-Johnsen model over random graphs with partially stubborn community
Lingfei Wang, Yu Xing, Karl H. Johansson
This paper studies the formation of final opinions for the Friedkin-Johnsen (FJ) model with a community of partially stubborn agents. The underlying network of the FJ model is symm…
Almost Exact Recovery in Gossip Opinion Dynamics over Stochastic Block Models
Yu Xing, Karl H. Johansson
We study community detection based on state observations from gossip opinion dynamics over stochastic block models (SBM). It is assumed that a network is generated from a two-commu…
Robust Data-Driven Kalman Filtering for Unknown Linear Systems using Maximum Likelihood Optimization
Peihu Duan, Tao Liu, Yu Xing +1
This paper investigates the state estimation problem for unknown linear systems subject to both process and measurement noise. Based on a prior input-output trajectory sampled at a…
Dynamic Curing and Network Design in SIS Epidemic Processes
Yuhao Yi, Liren Shan, Shijie Wang +2
This paper studies efficient algorithms for dynamic curing policies and the corresponding network design problems to guarantee the fast extinction of epidemic spread in a susceptib…
