🎲 The 2nd edition of UncertaiNLP is coming to EMNLP 2025 in Suzhou! A venue for work on uncertainty-aware NLP, from Bayesian inference to decision-making under uncertainty.

🗓 Direct submissions due: Aug 15
🗓 ARR commitments due: Aug 29

Details: uncertainlp.github.io

I also wonder whether non US-based people do not want to go to US-based conferences since Trump

Did they give a reason for the drop in US authors? 🤔

Isn't that still quite vague though? Because which kind of consumer device are we talking about 🙃

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.

The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

I’m petrified about today’s science news. Genetically modifying crabs to have cheetah genes? This could go sideways fast.

Congratulations!!! 🥳🥳🥳

Reading it right now!

This isn't even my final form ẞ

Inline citations with only first author name, or first two co-first author names.

If you're finishing your camera-ready for ACL or ICML and want to cite co-first authors more fairly, I just made a simple fix to do this! Just add $^*$ to the authors' names in your bibtex, and the citations should change :)

They talk about this in the Command A paper? arxiv.org/pdf/2504.00698?

Chat UI Energy Score - a Hugging Face Space by jdelavande Chat with an AI assistant and see how much energy your conversation uses. Get real-time energy estimates compared to everyday activities like phone charging or driving.

Such an important project: @hf.co put up an interactive site to see the real time energy costs of chatting with genAI.

"Calculate how much water it would take to cool the world's largest supercomputer" took 13% of a smartphone battery. Complete with hallucinations. 😆

I wonder what kind of unhinged emails overleaf support must be getting right now

AI researchers when overleaf is down and they rediscover life outside of academia

Aleatoric and epistemic uncertainty are clear-cut concepts, right? ... right? 😵‍💫 In our new ICLR blogpost we let different schools of thought speak and contradict each other, and revisit chatbots where “the character of aleatory ‘transforms’ into epistemic” iclr-blogposts.github.io/2025/blog/re...

💡 New ICLR paper! 💡
"On Linear Representations and Pretraining Data Frequency in Language Models":

We provide an explanation for when & why linear representations form in large (or small) language models.

Figure showing uncertainty quantification on the Iris dataset using ensemble and MC Dropout models. On the left, images of three Iris species are displayed: (a) Iris setosa, (b) Iris versicolor, and (c) Iris virginica. The center scatter plot visualizes sepal length vs. sepal width with data points colored by class and black stars representing test points. Triangular plots labeled ①, ②, and ③ highlight predicted class probabilities for the test points, showing density heatmaps of prior predictions and overlayed ensemble (orange x) and MC Dropout (purple dot) predictions in a probability simplex. A legend identifies each Iris species and the test points.

I ascribe the success mostly to what might my nicest figure. Took an eternity to write, was rejected twice, and every new paper that came out during the time of writing that I had to read it felt like my last nail (but I didn't learn since I am working on another survey rn)

Congrats!! 🥳

Today we are releasing Kaleidoscope 🎉

A comprehensive multimodal & multilingual benchmark for VLMs! It contains real questions from exams in different languages.

🌍 20,911 questions and 18 languages
📚 14 subjects (STEM → Humanities)
📸 55% multimodal questions

Very cool!

Oh my gosh finally 😱

I couldn’t find a copy of hacking online earlier :-( Hora also seems comparatively late to the shafer reference from my other reply

Went down that direction already and got stuck 😬 I think it seems like one of these facts that appears as common knowledge so many people don't even add a citation to it

In an earlier work in 1976, he argues for these terms based on some ideas of Poisson (see second screenshot). But I think (???) that this might be the time these terms were defined (also see how aleatoric was actually named aleatory), since I cannot find any occurrences of the phrases before 1975.
