Attended my first @netsciconf.bsky.social last week and it was amazing!
A highlight was the HONAI satellite that brought together the network science and machine learning communities.
...and who needs NeurIPS mugs if one can have NetSci toilet paper?

Today, I gave a talk on Expressive Graph Representations via Homomorphisms in Subhankar Mishras lab at NISER, India.
For all those (all - 50) people who missed it at the LoG Paris meetup, there is now a recording available:

He will lecture on LLMs as GNNs – a topic which received quite some attention at our last session.
Specifically, we will learn how Graph ML tools can help understand LLM generalisation

Ever needed a graph neural network with maximal expressivity on almost all molecules (aka 𝗼𝘂𝘁𝗲𝗿𝗽𝗹𝗮𝗻𝗮𝗿 graphs)?
Turns out you only need a simple graph transformation called 𝐶𝐴𝑇!

Weisfeiler and Leman go Loopy: A New Hierarchy for Graph Representational Learning
Cycles are important for predictive tasks on chemical molecules. We allow message passing along neighboring paths. Our architecture can subgraph-count cycles and homomorphism-count cactus graphs.
