Title: Social Opinion Formation, Polarization, and Evolution

Speaker: Siyang Leng

Abstract: Modeling and analyzing social phenomena such as fashion trends, news dissemination, and information cocoons has long been an important issue in interdisciplinary research within fields like social science, information science, and complex systems. Human individuals continuously update their opinions of events and evolve by observing the external environment and communicating with each other, leading to the emergence of group consensus and collective decision-making. This talk focuses on the underlying principles of information dissemination and consensus formation in social networks. It also introduces the research history of social learning theory, highlighting its broad applications in computer science and engineering, as well as our team’s recent progress in this area, revealing intriguing social patterns.
