New paper! The Linear Representation Hypothesis is a powerful intuition for how language models work, but lacks formalization. We give a mathematical framework in which we can ask and answer a basic question: how many features can be stored under the hypothesis? 🧵 arxiv.org/abs/2602.11246

Our paper on algorithmic collusion was featured in a Quanta article! www.quantamagazine.org/the-game-the...

New paper on collaborative prediction just dropped!! This was a ton of fun to work on and the results are ✨nifty✨

I am incredibly baffled why standard reporting agencies (eg NYT) are leading w illegal immigrants in all their articles about this, when by my reading it is a huge swath of people not usually targeted by the "illegal immigrant" rhetoric who are additionally impacted.

The beautiful irony of this postdoc application I'm filling out that is specifically for minority applicants and which asks lots of questions about my gender identity also being the only one I've submitted thus far to specifically require my legal name all over the form. 😆

Does anyone have any favorite resources about the reliance on precedent in US law? It's something I've never fully grasped. As a silly computer scientist, my impulse is to say that correctness of logical reasoning should be independent of that which came before.

I regret to report that despite my initial horror of using starch gelation to achieve a good pan sauce, my recreation of this experiment tastes better than any unsuccessful attempt at cacio e pepe I have made thus far.

The fact that you get an AI overview on google before any other links leads to some fun slightly oxymoronic content.

Is there a word/phrase for the phenomenon of media disappearing from widespread access because it's only hosted on streaming services and those services can remove it randomly?

Reading a book on regulation in the early internet written in '99 and @globusharris.bsky.social is letting me borrow this excellent Y2K bookmark from the library to go with the theme, advertising the new digital library search technology. Which didn't yet include email support, but says soon will!

Much thanks to @gautamkamath.com @thejonullman.bsky.social and @adamsmith.xyz for organizing this!

Hey listen could FORC and FAccT maybe not be overlapping conferences every year? These are the two most relevant conferences to my research interests and I simply do not understand why they need to be on the same or nearly identical days.

How do people organize the research papers they read? My current strategy is a mess of papers in random places. I've tried organizing by topic but there's overlap and it ends up being ambiguous and too annoying to maintain.

Has anyone ever had to write a leadership statement for an academic job and if so, what did you include?
