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!).

The other paper accepted to @iclr-conf.bsky.social 2026 🇧🇷. Our work on replicable RL sheds some light on how to consistently make decisions in RL. @ericeaton.bsky.social @mkearnsphilly.bsky.social @aaroth.bsky.social @sikatasengupta.bsky.social @optimistsinc.bsky.social

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...

Oh cool! A student's been teaching me about LM benchmarks recently and might be doing her project on something related to evaluating evaluations. If you make your site public, I will def point her your way!

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
