Our new paper in #PNAS (bit.ly/4fcWfma) presents a surprising finding—when words change meaning, older speakers rapidly adopt the new usage; inter-generational differences are often minor.

📣 Life update: Thrilled to announce that I’ll be starting as faculty at the Max Planck Institute for Software Systems this Fall!
I’ll be recruiting PhD students in the upcoming cycle, as well as research interns throughout the year: lasharavichander.github.io/contact.html
I'm at #ICML in Vancouver this week, hit me up if you want to chat about pre-training experiments or explainable machine learning.
You can find me at these posters:
Tuesday: How Much Can We Forget about Data Contamination? icml.cc/virtual/2025...
Congrats!
Paper title "The Non-Linear Representation Dilemma: Is Causal Abstraction Enough for Mechanistic Interpretability?" with the paper's graphical abstract showing how more powerful alignment maps between a DNN and an algorithm allow more complex features to be found and more "accurate" abstractions.
Mechanistic interpretability often relies on *interventions* to study how DNNs work. Are these interventions enough to guarantee the features we find are not spurious? No!⚠️ In our new paper, we show many mech int methods implicitly rely on the linear representation hypothesis🧵
Have you ever wondered whether a few times of data contamination really lead to benchmark overfitting?🤔 Then our latest #ICML paper about the effect of data contamination on LLM evals might be for you!🚀
Paper: arxiv.org/abs/2410.03249
👇🧵
💡Beyond math/code, instruction following with verifiable constraints is suitable to be learned with RLVR.
But the set of constraints and verifier functions is limited and most models overfit on IFEval.
We introduce IFBench to measure model generalization to unseen constraints.
A blizzard is raging through Montreal when your friend says “Looks like Florida out there!” Humans easily interpret irony, while LLMs struggle with it. We propose a 𝘳𝘩𝘦𝘵𝘰𝘳𝘪𝘤𝘢𝘭-𝘴𝘵𝘳𝘢𝘵𝘦𝘨𝘺-𝘢𝘸𝘢𝘳𝘦 probabilistic framework as a solution.

We look behind the scenes, beyond the polished papers 🧐🧪

"Build the web for agents, not agents for the web"
This position paper argues that rather than forcing web agents to adapt to UIs designed for humans, we should develop a new interface optimized for web agents, which we call Agentic Web Interface (AWI).

Excited to share the results of my recent internship!
We ask 🤔
What subtle shortcuts are VideoLLMs taking on spatio-temporal questions?
And how can we instead curate shortcut-robust examples at a large-scale?
We release: MVPBench
Details 👇🔬
Congrats Sarah!! They are lucky to have you 💪

Do LLMs hallucinate randomly? Not quite.
Our #ACL2025 (Main) paper shows that hallucinations under irrelevant contexts follow a systematic failure mode — revealing how LLMs generalize using abstract classes + context cues, albeit unreliably.
📎 Paper: arxiv.org/abs/2505.22630 1/n
Congrats Elinor!
Chain-of-Thought (CoT) reasoning lets LLMs solve complex tasks, but long CoTs are expensive. How short can they be while still working? Our new ICML paper tackles this foundational question.
Title slide: Processing Trans Languaging - Vagrant Gautam (they/xe), Saarland University, with a very brightly patterned background featuring colourful people and math symbols.
Come to my keynote tomorrow at the first official @queerinai.com workshop at #NAACL2025 to hear about how trans languaging is complex and cool, and how this makes it extra difficult to process computationally. I will have SO many juicy examples!
Deadline extended! ⏳
The Actionable Interpretability Workshop at #ICML2025 has moved its submission deadline to May 19th. More time to submit your work 🔍🧠✨ Don’t miss out!
Very interesting work! We also compared ICL and finetuning a while ago. You might find it relevant: aclanthology.org/2023.finding...
Check out Gaurav's video on their #NAACL paper and find @adadtur.bsky.social at the conference 👇
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!

I’m really excited about Diffusion Steering Lens, an intuitive and elegant new “logit lens” technique for decoding the attention and MLP blocks of vision transformers!
Vision is much more expressive than language, so some new mech interp rules apply:
💡 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.

Logo for MIB: A Mechanistic Interpretability Benchmark
Lots of progress in mech interp (MI) lately! But how can we measure when new mech interp methods yield real improvements over prior work?
We propose 😎 𝗠𝗜𝗕: a 𝗠echanistic 𝗜nterpretability 𝗕enchmark!
We also saw some interesting overthinking failure cases across various tasks in our work: arxiv.org/abs/2504.07128 Much work needs to be done to better understand the behavior of reasoning LLMs!
Paper title of the year so far. I will be back ... have to read the paper now. Great work @saxon.me !
