Robustness in Text-Attributed Graph Learning: Insights, Trade-offs, and New Defenses

ICLR 2026poster

While Graph Neural Networks (GNNs) and Large Language Models (LLMs) are powerful approaches for learning on Text-Attributed Graphs (TAGs), a comprehensive understanding of their robustness remains elusive. Current evaluations are fragmented, failing to systematically investigate the distinct effect…

Future Link Prediction Without Memory or Aggregation

NeurIPS 2025poster

Future link prediction on temporal graphs is a fundamental task with wide applicability in real-world dynamic systems. These scenarios often involve both recurring (seen) and novel (unseen) interactions, requiring models to generalize effectively across both types of edges. However, existing methods…

TGB-Seq Benchmark: Challenging Temporal GNNs with Complex Sequential Dynamics

ICLR 2025poster

Future link prediction is a fundamental challenge in various real-world dynamic systems. To address this, numerous temporal graph neural networks (temporal GNNs) and benchmark datasets have been developed. However, these datasets often feature excessive repeated edges and lack complex sequential dyn…
