Investigating GNN Expressiveness in Graph Generation Tasks
Imperial UROP 2023 Student Project – We propose an approach to improve GNN-based graph generative models including GCPN, GraphAF and GraphEBM, and investigate the correlation between GNN expressiveness in the graph prediction and graph generation contexts.

Will More Expressive Graph Neural Networks do Better on Generative Tasks?
We propose an approach to improve GNN-based graph generative models including GCPN, GraphAF and GraphEBM, and investigate the correlation between GNN expressiveness in the graph prediction and graph generation contexts.

Hybrid Graph: A Unified Graph Representation with Datasets and Benchmarks for Complex Graphs
We introduce the concept of hybrid graphs, a unified definition for higher-order graphs, and present the Hybrid Graph Benchmark (HGB), a collection of hybrid graph datasets with an extensible evaluation framework.

Task-Agnostic Graph Neural Network Evaluation via Adversarial Collaboration
We propose GraphAC (Graph Adversarial Collaboration) – a conceptually novel, principled, task-agnostic, and stable framework for evaluating GNNs through contrastive self-supervision, without the need of handcrafted augmentations.
