Centre for Networked Intelligence

Dear All, Networks Seminar, supported by the Centre for Networked Intelligence, is a technical discussion forum in topics including but not limited to computer networks, machine learning, signal processing, and information theory. The seminar series has a webpage hosted at https://cni.iisc.ac.in/seminars/. You are invited to the following seminar held as part of this series. Title: Influence Enhancement in Opinion Dynamics Using Edge Modification: A Kron Reduction-Based Approach Speaker: Prof. Twinkle Tripathy, Assistant Professor, IIT Kanpur Time: 04:00 PM - 05:00 PM (IST) Date: 26 October 2026 Venue: Online on Zoom Zoom link: https://us06web.zoom.us/j/83388976389?pwd=XcpO3GhLxsR14a7SVbPx33HQQa1jbt.1 Zoom Meeting ID: 833 8897 6389, Pass Code: NSSIISc Webpage Link: https://cni.iisc.ac.in/seminars/2026-10-26/ <https://cni.iisc.ac.in/seminars/2026-10-26/> Abstract: 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 talk, we will address this problem under the Friedkin-Johnsen opinion dynamics model, wherein stubborn agents influence the opinions of other agents in the network. We propose to use edge modifications, specifically those which mimic the mechanism of recommendations in social networks. In such scenarios, topological properties of the network play a key role in increasing the influence of a desired stubborn agent. Hence, we will show that there exist topology-based conditions that identify the edge modifications that always increase the influence of a desired stubborn agent. Interestingly, the impact of the chosen edge modifications is robust to changes in parameters such as stubbornness and the interaction weights. Finally, we will demonstrate the effectiveness of our approach over the Erdos–Renyi random graph.
