CS ArXiv recently banned “review and position” papers, but what are those? Do they include more generated content? Who is most affected by this change? @yanai.bsky.social and I dug into the data to find out! Nearly 50% of Computers & Society papers might be censored, vs 3% of Computer Vision ‼️

🚨 New Study 🚨 @arxiv.bsky.social has recently decided to prohibit any 'position' paper from being submitted to its CS servers. Why? Because of the "AI slop", and allegedly higher ratios of LLM-generated content in review papers, compared to non-review papers.

Any good tutorials/guides on how to code with LLMs? What I found so far targeted folks who don't know what they are, mostly setting expectations and saying what LLMs can or cannot do. I'm beyond that. I'm looking for best practices. Kind of design patterns for vibe coding.

A strange trend I've noticed at #ACL2025 is that people are hesitant to reach out to papers/"academic products" authors. This is unfortunate for both parties! A simple email can save a lot of time to the sender, but is also one of my favorite kind of email as the receiver!

Had a really great and fun time with @yanai.bsky.social, Niloofar Mireshghallah, and Reza Shokri discussing memorisation at the @l2m2workshop.bsky.social panel. Thanks to the entire organising team and attendees for making this such a fantastic workshop! #ACL2025

I had a lot of fun contemplating about memorization questions at the @l2m2workshop.bsky.social panel yesterday together with Niloofar Mireshghallah and Reza Shokri, moderated by @pietrolesci.bsky.social who did a fantastic job! #ACL2025

What if you could understand and control an LLM by studying its *smaller* sibling? Our new paper introduces the Linear Representation Transferability Hypothesis. We find that the internal representations of different-sized models can be translated into one another using a simple linear(affine) map.

I really like this take. Academia and the open source community should embrace transparency in data, even in the cost of the issues that come with it. These issues should be of course studied and documented, but not used as an indicator or a signal to shut down the whole operation.

Fully open machine learning requires not only GPU access but a community commitment to openness. (Some nostalgic lessons from the ImageNet decade.)

Prompting is our most successful tool for exploring LLMs, but the term evokes eye-rolls and grimaces from scientists. Why? Because prompting as scientific inquiry has become conflated with prompt engineering. This is holding us back. 🧵and new paper with @ari-holtzman.bsky.social .

Check out our take on Chain-of-Thought. I really like this paper as a survey on the current literature on what CoT is, but more importantly on what it's not. It also serves as a cautionary tale to the (apparently quite common) misuse of CoT as an interpretable method.

Excited to share our paper: "Chain-of-Thought Is Not Explainability"! We unpack a critical misconception in AI: models explaining their steps (CoT) aren't necessarily revealing their true reasoning. Spoiler: the transparency can be an illusion. (1/9) 🧵

I'll be at #NAACL2025: 🖇️To present my paper "Superlatives in Context", showing how the interpretation of superlatives is very context dependent and often implicit, and how LLMs handle such semantic underspecification 🖇️And we will present RewardBench on Friday Reach out if you want to chat!
