Topic: Representation Learning for Graphs and Dynamic Graphs

Speaker: Prof. SONG Le, Georgia Tech

Date and Time: 10:00 am – 11:00 am, March 8, 2019

Venue: Boardroom, Dao Yuan Building

Abstract：

Graphs and dynamic graphs have become a universal language in science and technology for describing structures in data, modeling complex systems, and expressing symbolic knowledges. How to represent complex graphs, such that models and algorithms over graphs can become more effective? In this talk, I will describe a learning framework for graph representation by neuralizing message passing operators. I will show that the learned representation can be thousands of times more compact than hand-crafted features, and such representation can be learned efficiently for very large graphs and used with reinforcement learning for solving challenging combinatorial optimization problems. In the end, I will also explain how to understand such deep representation over graphs.
