We are organizing the CoLearn workshop in Aachen (colearn.rwth-aachen.de), fostering exchange between combinatorial optimization and machine learning, with a fantastic keynote speaker lineup, including A. Lodi, N. Megow, M. Skutella, G. Schäfer, Y. Zhang, and J. Toenshoff.

This will be great newgraphperspectives.com.

Graph Learning Meets Theoretical Computer Science Graph learning is a branch of machine learning focusing on developing and studying methods to make predictions for vertices, subgraphs, or entire graphs. The field of graph learning has already reveal...

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.

Thanks, Leo!

Position: Graph Learning Will Lose Relevance Due To Poor Benchmarks While machine learning on graphs has demonstrated promise in drug design and molecular property prediction, significant benchmarking challenges hinder its further progress and relevance. Current bench...

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.

Joint work with Antonis Vasileiou, Ben Finkelshtein, Ron Levie, and Floris Geerts.

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

Want to know about the current understanding of the generalization abilities of GNNs? Please have a look at our survey paper arxiv.org/abs/2503.15650.

Gott sei Dank! :P

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.
