Model Agreement via Anchoring
Numerous lines of aim to control $\textit{model disagreement}$ -- the extent to which two machine learning models disagree in their predictions. We adopt a simple and standard notion of model disagree...

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!

Do you have recent work on differential privacy? Submit it to TPDP 2026 in Boston, whose deadline is in ~2 weeks. TPDP is a lightly reviewed workshop, whose main purpose is getting researchers in DP together in one place. Dual submissions allowed (and encouraged!).

DC-area folks: lots going on right now, but this rally to save PEPFAR is worth a look. The cruelties and robbery are worth fighting in aggregate and important to fight in specific. pepfarreport.org/event

Alex Tolbert is running a stellar conference next week at Emory that I am bummed to be missing out on. The speaker lineup is especially remarkable- spanning theoretical computer science to machine learning to law to philosophy. You should go and enjoy it for me. 39893947.hs-sites.com/aiethicsconf...

Dear Google search. I don't mean private parties. I never mean private parties. I am neither hip nor a socialite. It's private parities. I meant what I said. Every time. Thank you.

Anyone have a favorite proof of Hoeffding's lemma that's more intuitive than applying the AMGM inequality to a term of a Taylor expansion of a function plucked from The Land of It Made Things Work? I'm happy to trade constants for intuition/simplicity

Just heard a Roosevelt Institute economist say, "the question of the bad vibes is actually an international question," and I for one am grateful our greatest minds are looking into why, precisely, the vibes have been off (globally) and what we might do about it

We've got a new paper in which we solve Principal/Agent problems without any common prior assumptions. The abstract has some CS Jargon, so I asked ChatGPT to translate it for 1) an economic theorist, 2) a "development economist in a business school", and 3) a bright 3rd grader.

Extremely disappointed that I'm not staying in NH long enough to visit the American Precision Museum, which is undoubtedly cool and weird, and so I will never learn what this is.
A gadget with wheels, gears, and cranks, which presumably enables a task to be completed with high precision, but I'll never know what task, because I cannot visit the American Precision Museum.

Tried to go to my visitor office, but it was filled with sleeping undergrads who were all tuckered out from the hackathon that I guess is happening today? I let them rest, but as payment, I am helping myself to some funky fresh GNU stickers, coffee, and snacks #snackathon23
Upper left: a sticker with the GNU gnu and Tux the penguin in superhero gear, flying towards the viewer.

Upper right: a sticker with a pixelated image of "Gnu Emacs" printed on a sink for reasons I'm sure I would understand if I was more hip.

Lower: a Free Software Foundation sticker.

📊 New week, new (bi)weₐᵉkly quiz, and new format! It's been a while! This week, we're looking at NUMBERS, and how to (badly) estimate them! I have written 5 snippets of code, each meant to estimate (via some random🎲sampling) a value. Your goal: figure out which, and why. 1/
A plot showing the simulations for the 5 quantities (5 different plots, each converging, slowly or not, to 5 values).
