Toward Interpretable and Stable Graph Neural Networks
Description
Graphs are ubiquitous data structures in numerous domains, such as social science (social networks), natural science (physical systems, and protein-protein interaction networks) and knowledge graphs. As new generalizations of traditional deep neural networks to graph structured data, Graph Neural Networks (or GNNs) have demonstrated the power in graph representation learning and have permeated numerous areas of science and technology. However, GNNs also inherited the drawback of traditional deep neural networks, i.e., lacking interpretability. Moreover, graph neural networks are vulnerable to adversarial attacks. These drawbacks have raised tremendous concerns to adopt GNNs in many critical applications pertaining. Thus, this project aims to tackle the major drawbacks of GNNs and greatly enlarge their usability in critical applications. To achieve the research goal, this project systematically investigates advanced principles for new mechanisms to interpret GNNs, understand their vulnerabilities and develop robust GNNs. The proposed research extends the state-of-the-art GNNs to a new frontier, investigates original problems that entreat innovative solutions and paves the way for a new research endeavor effectively tame graph mining.
