Abstract
Graph neural networks (GNNs) have been widely used on graph-structured data, but they also face a series of challenges in solving real-world problems, including scarcity of labeled data, scalability issues, and potential bias. In this talk, I will recap my research efforts in tackling these challenges and empowering GNNs on real-world tasks. First, I will start from a specific domain, AI for chemistry, with a focus on addressing the issue of limited labeled datasets commonly encountered in various chemical tasks. Then, I will move to general scenarios and address the inherent issues of GNNs, using scalability as an example. Finally, I will present my future vision and ongoing work aimed at advancing interdisciplinary research and promoting the fairness and robustness of GNNs.
