Developing statistical machine learning methods for predictions on graphs has been a fundamental problem for many applications such as semi-supervised node classification and link prediction on knowledge graphs. Such problems have been extensively studied by traditional statistical relational learning methods and recent graph neural networks, which are attracting increasing attention. In this talk, I will introduce our recent efforts to combine the advantages of both worlds for prediction and reasoning on graphs. I will introduce our work on combining conditional random fields and graph neural networks for semi-supervised node classification (Graph Markov Neural Networks, ICML'19) and also recent work on combining Markov Logic Networks and knowledge graph embedding (Probabilistic Logic Neural Network, in submission) for reasoning on knowledge graphs. Key Takeaways: (1) Reasoning is important for decision making and missing in existing deep learning systems (2) In this presentation, I will introduce our recent works on combing traditional statistical relational learning and recent graph neural networks for relation reasoning (3) A more general direction for the future is how to combine traditional symbolic logic rule based approaches with deep neural networks for reasoning?
