Yesterday @tgnassou.bsky.social successfully defended his PhD thesis on domain adaptation of signals and in particular EEG. Huge congrats to him for all his work and his wonderful slides. It was a pleasure to be his advisor with @agramfort.bsky.social and I can't wait to see what he will do next!

The Amphora of Great Intelligence (AGI) Part 2 #webcomic #krita #miniFantasyTheater

What if we did a single run and declared victory

Competitor enters a major AI competition (RNA folding) GPU poor so can't train an AI Builds a "classic" eng pipeline instead. (90s tech) Wins and beat everyone using DL 💀 Their winning "hybrid" model had an AI in it. Their original one did not and had a higher score So they won despite the AI 😂

Probably the best paper title of my career. To read with the Indiana jones soundtrack. And yes we solved and differentiated quite well 80 millions (small) Fused Gromov Wasserstein problems per epoch using a neural network on GPU.

Our latest paper “The Quest for the GRAph Level autoEncoder (GRALE)” was accepted at NeurIPS 2025! arxiv.org/abs/2505.22109 🏆 GRALE 🏆 can encode and decode graphs into and from a shared Euclidean space. Training such a model should require solving the graph matching problem but...

A speech about what drives me, how science and open source are bitter victories, unable to make improve the world if society does not embrace them for the better: gael-varoquaux.info/personnal/a-...

It's a great discussion because we all have different interpretation of what this means and what the consequences are. Myself, I have absolutely no doubt that scaling works. If you have all the videos in the world and are able to train a model that can recall and merge any of them, then for sure...

Figure 1. Happy ML researcher and open source developer presenting his toolbox SKADA at PyData Paris. Congrats @tgnassou.bsky.social the presentation was awesome!

I am happy to share that our paper "Unsupervised Learning for Optimal Transport plan prediction between unbalanced graphs" was accepted at Neurips 2025 ! 🥳 Huge thanks to my co-authors @rflamary.bsky.social and Bertrand Thirion ! arxiv.org/abs/2506.12025 (1/5)

Did not know that all authors that submit 3 ICLR of more must be reviewers with 6 (or more?) papers. Seems fair to review 2 papers per submission but after the full NeurIPS summer (and rejection) I would have appreciated a reduced load to do them better (I say that as an ICML 2025 top reviewer).

I missed it last month! Very happy to present POT next week at PyData Paris.

SKADA is a beautiful software for Domain Adaptation in python with many shallow and deep methods implemented, it is 100% compatible with @scikit-learn.org models and pipelines and with @pytorch.org for deep learning methods.

Our article "Large-scale semi-discrete optimal transport with distributed Voronoi diagrams" (with Nicolas Ray, Quentin Merigot and Hugo Leclerc) just got accepted by Journal of Computational Physics. Pushing the limits of Optimal Transport by several orders of magnitude !

I'm thrilled to announce that my #ERCStG project **Optinfinite : Efficient infinite-dimensional optimization over measures** has been accepted. Thank you @erc.europa.eu ! Many thanks also to @crestumr.bsky.social @ipparis.bsky.social for they support, as well as to my collaborators and friends.

To: Reviewer 2 My name is Inigo Montoya You killed my paper Prepare to die

Thanks for raising this issue. As someone on the authors' and reviewers' side, this feels like a violation of the reviewing process. One might wonder, “Why do we put so much time and effort into the peer-review process if decisions are ultimately made arbitrarily?”.

I wrote about the tragic death of Adam Raine and the venal negligence of "AI Safety." www.argmin.net/p/the-banal-...

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.

A university and an academic publisher walk into a bar. The publisher orders a pint, sells it back to the university, asks the barman to pay the bill.

🤖 Dang, we are seeing increasing evidence of this: The use of generative AI negatively affecting critical thinking. www.bloomberg.com/news/article... Paging @emilymbender.bsky.social, one of the few people who started warning the public about this years ago...

By now it's just too much information (reviews, rebuttal back-and-forth, final reviewer justification, final author remark). On average, for each paper I'm reviewing there is a discussion of ~10 pages. It's almost impossible to keep track of everything.

I came here to kick ass AND chew bubble gum And I’m all out of gum Therefore it is impossible to kick ass AND chew bubble gum I should have come to kick ass XOR chew bubble gum

Why #NeurIPS PC? Why? We already have days of reading to do including reviews, responses, responses to responses and confidential comments to AC. Do you really think a "Final Remark" that tells me to accept the paper will help? Let me just do my AC job during august while everyone is on vacation!

Hum I have some scores disappearing on openreview on my #NeurIPS papers. Do you have the same? Maybe it means the scaore has been edited? If this is to hide the score until final decision, this seems like a bad idea (we know how to do data imputation in the community)

Everybody misses the 1-page rebuttal. These lengthy forum style comments are a nightmare: a nightmare for the authors who spend way too much time writing them, a nightmare for the reviewers who spend too much time understanding them, a nightmare for the ACs who will have to summarize all. Stop it!

As a #NeurIPS AC I did a little stat. Paper reviews+responses in my batch contain 515k characters and 75k words. This is without including papers themselves or authors/reviewers discussions. So please be nice to your AC, we are doing our best. Also I miss the one page PDF response of old ICML.

This prompt injection for GEMINI CLI is just fascinating. It's crazy that because of LLM, hackers can now do social engineering without a human in the loop. But I guess giving execution rights to an LLM is already a big humain failure anyways. arstechnica.com/security/202...

SKADA-Bench : Benchmarking Unsupervised Domain Adaptation Methods with Realistic Validation On Diverse Modalities, has been published published in TMLR today 🚀. It was a huge team effort to design (and publish) an open source fully reproducible DA benchmark 🧵1/n. openreview.net/forum?id=k9F...

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?

This is awful! We need to treat our scientists better if we want to do good science. This means consistent funding for tenure that allows time for risky but novel discoveries and not only short-time projects and infinite post-docs. www.science.org/content/arti...

✨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

@rflamary.bsky.social 's keynote at CAp'25 was a blast! A short summary in the linked post below...

The most important aspect when facing data shift is the type of shift present in the data. I will give below a few examples of shifts and some existing methods to compensate for it.🧵1/6

Very honored to have given the keynote at the CAP 2025 conference in Dijon this morning. I talked about Domain adaptation, DA benchmark and applications of DA to sleep stating. Mostly work from the PhD of @tgnassou.bsky.social For those interested here are the slides remi.flamary.com/pres/OTDA_Ke...

Time to take a vacation!

Distributional Reduction paper with H. Van Assel, @ncourty.bsky.social, T. Vayer , C. Vincent-Cuaz, and @pfrossard.bsky.social is accepted at TMLR. We show that both dimensionality reduction and clustering can be seen as minimizing an optimal transport loss 🧵1/5. openreview.net/forum?id=cll...
