Pushed a big update to LM-class (v2025.2) -- this second version makes a much more mature resource Many refinements of lecture slides + significant improvements to the assignments Many thanks to @ch272h.bsky.social, Yilun Hua, and Shankar Padmanabhan for their work on the assignments

@colmweb.org discussion period ended, and now we entered the meta reviewing period. It's not simple getting reviewer engagement nowadays, but slow and steady we made descent progress, even if shy of the ideal of early and wholly. Progress bars -> 🧵

I would worry about the rate of false positives. The emergency system is already overloaded, and in general not efficient. My activity tracking is not exactly what you want to measure, but it shows everything is last minute

I am not convinced this is the best way to compute this, but here goes. Definitely n per reviewer is too small to get anything meaningful

Help me understand why it's different than "my multi-step decision process model is not perfect (i.e., biased), so it introduces bad/biased decisions into the output"... because I don't know if I want to start using "sabotage" instead of "error" in my papers

It's now public! My postdoc call is for the inaugural postdoc as part of this $10.5M gift for a new AI fellows program at Cornell. There's a lot more in this program, so more exciting things to happen here real soon! news.cornell.edu/stories/2025... Application: forms.gle/tiydAChgV1wL...

No surveys here, so I ran this on X. So this brings about the next question: why are we still doing two columns in some venues?! Or tiny fonts in others? We need templates that fit how people read: fonts, columns, margins, etc

Oh, and, yea, there are lovely scaling behaviors as well, both on performance and stability frontier! All credit to @giomonea.bsky.social In collaboration with @xkianteb.bsky.social and @abosselut.bsky.social

A lot of the heavy lifting of in-context learning (ICL) is thanks to the semantics of labels (i.e., "positive" for sentiment is much more meaningful than "label1"). Can you ICRL without any semantics? Yes, you can! -> solid lines, or even better with a few exemplars -> dashed lines

Yoav Artzi @yoavartzi.com · 18/02/2025
First, we got ICRL to work out of the box without any specialized inference methods. It is actually just a matter of sampling and prompt construction. So, (good) LLMs can RL in-context! Purple💜 curves ...

We recently pushed an update to our in-context RL paper. Usually, updates don't justify a post, but this one is exceptionally contentful -> 🧵 tl;dr: all the findings are stronger, and the behaviors are super cool! arxiv.org/abs/2410.05362

I don't have the time to do research along different segments, but quickly found this index for construction costs. Line items like building depreciation should account for this increase to be realistic. www.mortenson.com/cost-index?u...

The world has gone mental. Jiayi Pan does a (very!) cool experiment showing R1-like pipeline in a very restricted domain (this is amazing, and the right way to conduct such experiments). Then it escalates pretty quickly to a $30 reproduction 🤦‍♂️ I guess the VCs already signed over the billions

Can someone create pbcopy-file? Don't disappoint ChatGPT Seriously though, is there a way to copy a file to the clipboard so I can paste it somewhere in finder? The file itself, not its content or its path.

Is Llama3.3-70B trained from scratch? It sounds like it huggingface.co/meta-llama/L... So what's the cause of the delta from 3.2? Is online preference optimization just RLHF with an on-policy algorithm (~PPO)?

I am very excited about this work, and how strong the results are. Relying on natural and implicit interactions signals is challenging, but a serious game changer Part of the excitement is because this continues a research thread that started with my **first** paper from 2011 👴

No. Instructions become less diverse (and maybe more templat-ish), but they remain well understood by humans (actually better understood, because performance goes up) This is the older papers where we saw this first: arxiv.org/abs/2108.04812

Pretty interesting AI outline in the new GScholar extension. They really tried to make it a navigation aid, rather generating what would appear to be replacement summaries
