About Me

My name is Sungyong Seo and I am a Ph.D. student in the Computer Science Department of University of Southern California. I work on Machine Learning under supervision of Professor Yan Liu. I also spent time at the NYU Center for Data Science to collaborate with Professor Kyunghyun Cho.

I am interested in machine learning problems in general. More specifically, my research mainly focuses on principled techniques for extracting knowledge from the complex structures or networks and using it to build predictive models – in that way merging insights both from data mining and machine learning. Furthermore, combining the structural knowledge with temporal behaviors is the topic which I am interested in. I am working on the following topics:

  • Physics-inspired machine learning
  • Spatiotemporal data mining
  • Graph-based neural networks
