Combining perceptual learning and logic inference/symbolic reasoning has been a long standing goal of AI. Graph neural networks are powerful representation learning tools for graph data, including but not limited to social networks, molecular graphs and knowledge graphs. A natural question is whether graph neural networks hold the potential to combine perceptual learning and logic inference, and lead to the next turning point of AI. So far, the majority of research works in graph neural networks have been focused on designing neural architectures for specific applications. Concrete arguments are still missing for why graph neural networks may be the bridge between perception learning and logic inference. In this talk, I will provide two pieces of evidence, one on inductive logic programming and the other on lifted logic inference, and show that graph neural networks lead to new, efficient and effective algorithms for addressing these challenging problems. These results also suggest that graph neural networks indeed have the potential to advance AI to the next stage.


Le Song is an Associate Professor in the College of Computing, and an Associate Director of the Center for Machine Learning, Georgia Institute of Technology.
