The first GLOW poster session

Instead of the usual setup, we are organising a big Gather Town session where you can present a poster about your own graph-related ideas, project or paper. People can move around the space, drop into conversations, listen to pitches, and discuss — much more informal and exploratory!

This is open to everyone: whether you've been working on something for a while or want feedback on your early-stage ideas, there's a spot for you.

Applications are still open! If you’d like to claim a space in Gather Town, please fill in this form before October 7th: Googleform

See you there!🚀

LLMs as GNNs (to understand how they generalize)

recording available on Youtube

Problems such as efficient (length) generalization are highly relevant for building agentic systems, yet they have puzzled LLM researchers for several years. However, they can sometimes be obvious through the lens of graph representation learning. This is because LLMs are, by their design, vulnerable to generalization issues from a variety of geometric perspectives.

A typical GNN researcher will already likely have a solid understanding of most of these perspectives! In this talk, we will use this knowledge, and attempt to scale the mountain of LLM generalization ⛰️

Discussion Session on the Future of Graph Learning Research

We want to use the February session to discuss what kind of research we want to do in graph learning in the next years and where we can make the most impact. Similar questions have already been discussed at length on big stages at various conferences. However, we think it is time to have this discussion with all graph learning enthusiasts, in particular (incoming) PhD students and postdocs who are actively shaping the field and whose research comprises the majority of what will be the field of graph learning in the next years. Whether you are excited, skeptical, curious, or frustrated about graph learning, we want to hear what you have to say!
