Abstract:

Graph structured data are ubiquitous in the real world such as social networks, molecular graphs, and emerging among a plethora of other diverse domains. Therefore, it is of great research importance to design advanced algorithms for representation learning on graph-structured data to facilitate improved predictions across numerous computational methods. Graph Neural Networks (GNNs), which generalize the deep neural network models to graph-structured data, pave a new way to effectively learn representations at both the graph and individual node levels. We have significantly contributed to the fundamental research of GNNs by developing novel algorithms and practical research of GNNs by investigating their safety issues and real-world applications. This talk presents two fundamental about key operations of GNNs, i.e., graph filtering operation and graph pooling operation. It first presents some commonly used graph filtering operations and then demonstrates how they can be observed from a unified graph signal denoising perspective. This talk also introduces a graph pooling operation based on spectral graph theory, which helps GNNs learn better graph-level representations.
