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

Dennis Ulmer @dnnslmr.bsky.social · Jul 28

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

Dennis Ulmer @dnnslmr.bsky.social · Jul 22

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.

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 :)

github.com/tpimentelms/...

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

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

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.

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)

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.
