CS Seminar| Scaling Computational Social Science: Enabling Collective Learning and Discovery

Start Date: October 4, 2017
End Date: October 4, 2017

By Professor Nitesh Vijay Chawla (Notre Dame University, USA)
The individuals connect and interact in varied ways to form the structural backbone that drives society, innovation, and impact. These varied and diverse inter-connections form complex and heterogeneous networks, and positing an important research questions on how we can model them to drive a better understanding and predictability of the formation and evolution of such networks. I will present our research that answers these questions by developing novel computational models to discover the social strategies that inform network formation and evolution, and developing a novel structural diversity theory to explain the process behind link formation. We leverage these social strategies to learn models for link prediction. I will also discuss how modeling heterogeneous networks, derived from Big Data, can help explain societal impact through a understanding and predicting scientific impact of scholars. Finally, I will present our work on representation learning models for embedding heterogenous networks, such that we can discover feature representations that are not possible through human-driven feature engineering tasks. I will end with some grand challenge problems in computational social sciences at the nexus of big data, networks, social sciences, and machine learning, which truly require a multi-disciplinary approach to achieve success.
Biography: Nitesh Chawla is the Frank M. Freimann Professor of Computer Science and Engineering, and director of the research center on network and data sciences (iCeNSA) at the University of Notre Dame.
