报告题目:Echo Chambers and Post-Truth from a Complex Systems Perspective

Cristián Huepe 教授 (CHuepe Lab

报告时间:2019年4月19日星期上午9:30

报告地点:bat365在线中国官网登录入口 六层学术报告厅(致知楼3623)

报告摘要:

The recent emergence of echo chambers and post-truth can be understood through the quantitative study of collective opinion-formation dynamics on social networks. I will present a minimal complex adaptive network model that explains why both phenomena appear to be increasingly common in the internet era. Using numerical and analytical approaches, I will show that this model displays an absorbing state where the network splits into independent components, each with a different internal consensus, which correspond to the echo chambers that lead to post-truth. I will also discuss model extensions that can capture more subtle opinion dynamics and describe our recent analyses of Twitter data, aimed at validating and further developing our theoretical results.

报告人简介:

Crisitián Huepe obtained his PhD at the École Normale Supérieure in Paris, after completing undergraduate studies in his native Chile. He then worked as a postdoctoral researcher in Chicago, first at the University of Chicago and later at Northwestern University. Since 2006, Dr. Huepe has worked as an unaffiliated researcher, heading his own CHuepe Labs in Chicago, supported by various research funds like NSF. Prof. Huepe is currently an Adjunct Research Professor at Northwestern University, External Faculty at the Northwestern Institute on Complex Systems, and an associate researcher at Beijing Normal University. He has also been a guest scientist at the Max Planck Institute for the Physics of Complex Systems in Dresden, and some other research centers in Hong Kong, Mexico, and Santiago etc.

His working fields include: superfluidity, Bose-Einstein condensates, finite-time singularities, spatiotemporal chaos, defect dynamics, and Faraday waves, among others. Currently, his research focuses on active matter, collective motion, and complex networks, using approaches from nonlinear dynamics, nonequilibrium systems and statistical physics. His work has been featured in Science Daily, Focus Online, National Geographic Germany and Wired Magazine, among others.
