Temporal link prediction on the Temporal Graph Benchmark 2.0 (TGB 2.0) faces a scalability ceiling:
on the benchmark's three largest datasets, every existing embedding method runs out of memory or exceeds the time budget.
These large-scale graphs are the ones nearest real deployment scale, so failing on them is a real production limitation.
EdgeReMIND Achievements
EdgeReMIND sets the highest reported test mean reciprocal rank (MRR) on six of eight TGB 2.0 datasets and is the only relation-aware method that runs on all of them.
This linear memorization model, with learned per-relation weights over data-calibrated features, is therefore not merely a fallback where embeddings fail but a practical state-of-the-art baseline across the benchmark.
