Subgraph Gaussian Embedding Contrast for Self-Supervised Graph Representation Learning Graph Representation Learning (GRL) is a fundamental task in machine learning, aiming to encode high-dimensional graph-structured data into low-dimensional vectors. Self-Supervised Learning (SSL) meth...

We're also presenting our work "Subgraph Gaussian Embedding Contrast for Self-Supervised Graph Representation Learning", accepted in the Research Track.

📄 Paper: arxiv.org/abs/2505.23529

📌 Join us:

-Poster: Tuesday, 7–9 PM.
-Oral: Wednesday, 4:12–4:30 PM (Representation Learning II session).

I’m at @ecmlpkdd.org #ECML in Porto this week and happy to connect with anyone interested in the broader field of geometric deep learning (graph neural networks, simplicial neural networks, hypergraphs, graph generation, etc.).

I have the feeling some journals are replacing "major revisions" with "rejection with possible resubmission" to artificially reduce acceptance rate. I'd resubmit with a letter explaining why the suggestion is not valid or run the additional baseline (not sure though if it's an additional baseline).

Let's push for the obvious solution: Dear @neuripsconf.bsky.social ! Allow authors to present accepted papers at EurIPS instead of NeurIPS rather than just additionally. Likely, at least 500 papers would move to Copenhagen, problem solved.

Yes, this is unclear @euripsconf.bsky.social

EurIPS is coming! 📣 Mark your calendar for Dec. 2-7, 2025 in Copenhagen 📅

EurIPS is a community-organized conference where you can present accepted NeurIPS 2025 papers, endorsed by @neuripsconf.bsky.social and @nordicair.bsky.social and is co-developed by @ellis.eu

eurips.cc

We have an open internship position on socially aware navigation, human aware world models etc.

At @naverlabseurope.bsky.social in Grenoble (Meylan), France.

NeurIPS participation in Europe We seek to understand if there is interest in being able to attend NeurIPS in Europe, i.e. without travelling to San Diego, US. In the following, assume that it is possible to present accepted papers ...

Would you present your next NeurIPS paper in Europe instead of traveling to San Diego (US) if this was an option? Søren Hauberg (DTU) and I would love to hear the answer through this poll: (1/6)

Great initiative!

We could also put some effort in the conferences happening here in Europe, e.g. ECML, BMVC, GCPR, etc. It's also up to us to some extent.

Similar for Polytechnique, part of Institut Polytechnique de Paris: future open positions in AI for junior researchers. They come with a good starting package and research independence.
Contact me by email or DM even for informal discussions.
