Repetition Makes Perfect: Recurrent Sum-GNNs Match Message Passing Limit We provide first tight bounds for the expressivity of Recurrent Graph Neural Networks (recurrent GNNs) with finite-precision parameters. We prove that recurrent GNNs, with sum aggregation and ReLU act...

An interesting paper by Eran Rosenbluth and Martin Grohe, www.arxiv.org/abs/2505.00291, shows a connection between polynomial-time algorithms and recurrent GNNs.

This is my favourite "graph paper" of the last 1 or 2 years. We also need to start including non-NN baselines, e.g. fingerprints+catboost ---if the goal is real-world impact and not getting it published asap. I also recommend following @wpwalters.bsky.social's blog.

In arxiv.org/abs/2412.07106, we leverage modern graph similarityโ€”capturing the fine-grained geometry of MPNNs' feature spaceโ€”to derive generalization bounds for MPNNs. Our theory is broad, covering various aggregation and loss functions.

What Can Neural Network Embeddings Do That Fingerprints Canโ€™t?

very cool observations about using smiles/graphs vs fingerprints. TDLR; fingerprints only capture certain properties marginally, and their combinations can often give rise to something new/different.
