Graph Neural Networks Are More Than Filters: Revisiting and Benchmarking from A Spectral Perspective

ICLR 2025poster

Graph Neural Networks (GNNs) have achieved remarkable success in various graph-based learning tasks. While their performance is often attributed to the powerful neighborhood aggregation mechanism, recent studies suggest that other components such as non-linear layers may also significantly affecting…

Explaining Graph Neural Networks with Large Language Models: A Counterfactual Perspective on Molecule Graphs

EMNLP 2024finding

In recent years, Graph Neural Networks (GNNs) have become successful in molecular property prediction tasks such as toxicity analysis. However, due to the black-box nature of GNNs, their outputs can be concerning in high-stakes decision-making scenarios, e.g., drug discovery. Facing such an issue, G…

Deep Ensembles for Graphs with Higher-order Dependencies

ICLR 2023poster

Graph neural networks (GNNs) continue to achieve state-of-the-art performance on many graph learning tasks, but rely on the assumption that a given graph is a sufficient approximation of the true neighborhood structure. In the presence of higher-order sequential dependencies, we show that the tenden…
