New York City 8th graders choose from 900+ high schools to apply to, in a process that’s spawned Facebook groups and dozens of expensive consulting services. Our new paper shows how application behavior leads to disparities, and how to effectively intervene. 🧵 www.nature.com/articles/s44...

It was fun giving this tutorial. If you missed it, check out calibration-tutorial.github.io where all of our materials are available, including slides, hundreds of pages of lecture notes, an interactive demo, and an annotated reading list.

Great news, Gautam's tutorial isn't at the same time as me, @ncollina.bsky.social and @aaroth.bsky.social 's. Which means you can first go to his, learn how to unlearn, go to ours, then if you don't like anything you can unlearn it using your newfound knowledge! wow!

On Monday @ncollina.bsky.social @iraglobusharris.bsky.social and I are giving a tutorial at ICML on (multi)calibration and its applications. You can find slides and an annotated bibliography on the website: calibration-tutorial.github.io as well as an interactive demo of online calibration algs.

Are you at ICML next week? Feel like your decision-making for which sessions to attend might not be risk minimizing? Don't incur (swap) regret and come to my, @aaroth.bsky.social, and @ncollina.bsky.social's tutorial Monday on multicalibration, decision-making, and collaborative learning!

I have this vision to code up an app where I can enter in the names of ppl I meet at conferences and a blurb about how we met etc.

I have really enjoyed talking with Kenny about his work on alternative rec system mechanisms. This work offers a vision of user-powered concept exploration: imagine the social media feed equivalent of the joy of exploring wikipedia by navigating trails of hyperlinks from one article to the next.

The goal is not just to remove race from models. It's to build systems where race no longer adds predictive power — because the factors it proxies for have been directly measured and the inequities it captures have been addressed.

Computational approaches to removing race are often insufficient. Why? Race often correlates with (1) unmeasured but relevant factors, like genetic traits (which should be measured directly) and (2) systemic disparities, like racism (which should be addressed, not adjusted for).

I really like this thoughtful piece by @dmshanmugam.bsky.social @emmapierson.bsky.social @sidhikabalachandar.bsky.social and others on how removing race from clinical algorithms is not necessarily the anti-racist choice it is purported to be, because race often has predictive power.

Neural networks are highly non-convex, so approximate error minimizers need not look anything like each other in parameter space. But we show that nevertheless (for many model sizes) approximate error minimizers must closely agree in function/prediction space despite this!

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

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.

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

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!

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.
