It may only be a band-aid, but we have just announced our new "Salon des Refusés" sessions for papers rejected due to space constraints: bsky.app/profile/euri...

Oh come on, a #NeurIPS rejection based on sensible, well-argumented reviews which show an understanding of the paper and its limitations? HOW AM I SUPPOSED TO COMPLAIN NOW?

"Like all good stories, the tale of EurIPS begins in the kitchen…"

📣📣📣 We are proud to announce our #EurIPS Affinity Events which will take place during the main conference days. Our Affinity Workshop Chairs have accepted three great proposals from well-renowned organizations @wimlworkshop.bsky.social Learning Theory Alliance @queerinai.com See you in Copenhagen!

📢 Interested in doing a PhD in generative models 🤖, AI4Science 🧬, Sampling 🧑‍🔬, and beyond? I am hiring PhD students at Imperial College London for the next application cycle. 🔗See the call below: joeybose.github.io/phd-positions/ ✨ And a light expression of interest: forms.gle/FpgTiuatz9ft...

Søren Hauberg (DTU) gives a quick tour of the site of EurIPS 2025: Bella Center, which features its own Metro stop, 13 min. from the airport, 9 min. to the center of town 🚊

The workshops focused on (in chronological order): - Variational Inference (youtube.com/playlist?lis...) - Optimal Transport (youtube.com/playlist?lis...) - Parallel Computing (youtube.com/playlist?lis...), and - Computational Physics (youtube.com/playlist?lis...).

#EurIPS sure is community-driven! Across our Calls for Workshops and Affinity Workshops we received a whopping 50+ proposals! Our Workshop and Affinity Workshop Chairs are now busy reviewing and discussing all proposals, and we plan to have the decisions ready mid-September 🤞

We just wrapped up the 5th Summer Geometry Initiative (SGI), bringing 30 Fellows to our cohort of 150+ alumni, who go on to PhD/MS programs, industry jobs, and more. Despite overwhelming success, SGI26 is uncertain thanks to the changing funding landscape. Please help by helping identify sponsors!

Friday afternoon! Finally time to look back at a busy week, and ask oneself — "wait, what did I do, again?"

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.

Interested in #topological deep learning (TDL) but not sure where to start? 🍩🤖 Check out #TopoBench, a comprehensive, modular library that benchmarks a wide variety of TDL models across diverse datasets. Thrilled to see it accepted at DMLR! Code+Papers: geometric-intelligence.github.io/TopoBench/

We can’t wait to see what the community builds with TopoBench! Star our repo, read the paper, and bring reproducibility to your TDL research. Contributions and feedback are welcome! #OpenSource #Python #AcademicTwitter

This was a massive team effort! Developed & led by @levtelyatnikov.bsky.social , @gbg141.bsky.social , Theodore Papamarkou. With major contributions from @Marco Montagna, Mustafa Hajij, Ghada Zamzmi, Michael T. Schaub, @ninamiolane.bsky.social , & @sscardapane.bsky.social , and many others!

Delighted to announce TopoBench has been accepted to DMLR! It’s a modular library for Topological Deep Learning, built to provide reproducible, cross-domain benchmarks and accelerate research. GitHub: github.com/geometric-in... #AI #DeepLearning

It is very refreshing seeing the start of a summer school be about Ethics in AI calling out the hype on GenAI as the frontier of human reasoning. Listening to this I am reminded of Feyerabend… “The only absolute truth is that there are no absolute truths” #EDS2025

📢 Save the date! Join us for the next @ellis.eu x UniReps Speaker Series! 📅 27th August – 16:00 CEST 📍https://ethz.zoom.us/j/66426188160 🎙️ Speakers: Keynote by @lelandmcinnes.bsky.social & Flash Talk by Yu (Demi) Qin 🔔 Stay updated by joining our Google group: groups.google.com/u/2/g/ellis-...

In the 20th century, non-Euclidean geometry transformed how we model the world with pen and paper. Now, it is disrupting how we model the world with machines. Learn more in our illustrated guide to non-Euclidean ML and AI👇

The world is a beautiful and fragile place that we are allowed to enjoy temporarily and should feel responsible for. It’s regrettable that we (the ML community) don’t manage to have decentralised conferences across the globe (look at you, @neuripsconf.bsky.social). Let's be better together!

🚀 TGLib is now on PyPI! Our open-source library for efficient temporal graph analysis is now easy to install (Linux): pip install temporalgraphlib 📄 Paper: arxiv.org/abs/2209.12587 💻 Code: gitlab.com/tgpublic/tglib #TGLib #TemporalGraphs #Python #OpenSource #NetworkScience

:0 wow pretty pictures!

Speaking from personal experience, the talks given by @pseudomanifold.topology.rocks are next level! Definitely a must see by @unireps.bsky.social !

EurIPS includes a call for both Workshops and Affinity Workshops! We look forward to making #EurIPS a diverse and inclusive event with you. The submission deadlines are August 22nd, AoE. More information at: eurips.cc/call-for-wor... eurips.cc/call-for-aff...

Great blog post on rotary position embeddings (RoPE) in more than one dimension, with interactive visualisations, a bunch of experimental results, and code!

🍇Happy to share GRAPES 🍇 Make GNNs work on large graphs by learning an expressive and adaptive sampler 🚀 Excellent work led by Taraneh Younesian now in TMLR! openreview.net/forum?id=QI0...

Topology is cool, check it out!

I love the #eurips initiative! But to live up to its potential, it should be accepted an official #neurips conference location (similar to Mexico City) and not just an addon! Then we would save C02, rather than adding to it!!! What can we do to achieve this?

Allowing a venue in Europe is a great idea but enforcing in-person presentations in the US kinda defeats the purpose, hopefully these conditions are relaxed in the future 🙏

✨Thrilled to see EurIPS launch — the first officially endorsed European NeurIPS presentation venue! 👀 But NeurIPS now requires at least one author to attend in San Diego or Mexico (and not just virtually as before). This is detrimental to many. Why not allow presenting at EurIPS or online? 1/4

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

NeurIPS is endorsing EurIPS, an independently-organized meeting which will offer researchers an opportunity to additionally present NeurIPS work in Europe concurrently with NeurIPS. Read more in our blog post and on the EurIPS website: blog.neurips.cc/2025/07/16/n... eurips.cc

EurIPS + ELLIS UnConference is coming to Copenhagen! 🇩🇰

New research from MIT found that those who used ChatGPT can’t remember any of the content of their essays. Key takeaway: the product doesn’t suffer, but the process does. And when it comes to essays, the process *is* how they learn. arxiv.org/pdf/2506.088...

The ICLR 2025 MLMP Best Paper Award, along with 2k GPU-hours from Nebius, goes to "On Incorporating Scale into Graph Networks"! Congratulations, Christian Koke, Yuesong Shen, @abhi-rf.bsky.social, Marvin Eisenberger, @pseudomanifold.topology.rocks, Michael M. Bronstein, @dcremers.bsky.social!

I can’t believe we just learned in 2025 that Dijkstra’s algorithm is not optimal. Why did I even bother learning how to pronounce it? arxiv.org/abs/2504.17033

🚨 New preprint from the lab! Discover fast topological neural networks, that leverage higher order structures without the usual computational burden! By @martinca.bsky.social @gbg141.bsky.social @marcomonga.bsky.social @levtelyatnikov.bsky.social @ninamiolane.bsky.social

At last Topological Neural Networks are fast🚀 HOPSE builds an encoder for combinatorial complexes, enabling topological deep learning (TDL) w/o the usual computational cost. A major step forward for TDL! @martinca.bsky.social @gbg141.bsky.social @marcomonga.bsky.social @levtelyatnikov.bsky.social

Absolutely proud of this work! Huge thanks to @gbg141.bsky.social @ninamiolane.bsky.social @marcomonga.bsky.social — and of course @martinca.bsky.social, who drove the project, learned on the fly, and kept the enthusiasm high at every turn!
