GraphML News (June 24th)

A plenty of news, finally.

There is going to be a GraphML community meetup at ICML’23 similar to that at ICML’22 and NeurIPS’22, feel free to drop by if you are at the conference. More details are to follow in the LoG2 slack.

Michael Bronstein, Francesco Di Giovanni and Ben Gutteridge wrote a new blogpost on Dynamically Rewired Delayed Message Passing - an approach to address over-squashing and improve long-range capabilities of GNNs. vDREW is based on the idea of sparse skip connections where a node can have a direct access to its k-hop neighbors but delayed in time. Good to see our long-range LGRB dataset gaining more traction in the community 🙂

New PhD thesis: Cristian Bodnar, the author of message passing architectures using simplicial complexes, cellular complexes, and neural sheaves, published his work on Topological Deep Learning: Graphs, Complexes, Sheaves. This is an excellent introduction to topology and topological DL, highly recommended.

LLMs can instruct robots to create chemical compounds: Andrew White presented a nice demo of ChemCrow - an agent that goes from natural language instructions to a sequence of real robotic actions to synthesize something. The authors synthesized 3 organocatalysts and even an insect repellent.

Weekend reading:

Equiformer V2: Improved Equivariant Transformer for Scaling to Higher-Degree Representations feat. Tess Smidt - the next and faster version of the famous and quite popular Equiformer (ICLR’23).

Symmetry-Informed Geometric Representation for Molecules, Proteins, and Crystalline Materials feat. Shengchao Liu, Anima Anandkumar, and Jian Tang - introduces Geom3D, a massive suite of datasets and 2D/3D geometric models that work on molecules, proteins, and even crystals. The repo offers 10 datasets, 35 models, and 14 pre-training methods.
