Come hang out with us at COLT 2025 and think about crafting and communicating your research agenda!

You are a continual inspiration to me, I hope you know this

Congrats to Russell!! 🎉

Also congratulations!!

Is this in your office, and if so, when can I come pay my respects to the norm balls?

Foggy Bottom Demonstration Friday Rubio promised waivers, but the system is broken. Join us Friday, March 7th, for a protest to restore PEPFAR at Foggy Bottom.

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.

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!

My turn to ask: what class?
Also, you didn't happen to snap a white board pic, did you?

The Algorithmic Foundations of Adaptive Data Analysis Fall 2017, Taught at Penn and BU

These are the course notes I'm borrowing heavily from adaptivedataanalysis.com

Theory of Replicable ML. It's a mix of topics from Aaron's and Adam Smith's course on adaptive data analysis + recent work on formal algorithmic replicability. jess-sorrell.github.io/Courses/Repl...

Your timing's great, I just showed my class Moritz's result today! (Borrowing @aaroth.bsky.social's notes.) Gonna go share your post on Canvas :)

Just started rereading IJ and the whole subsidized time thing sounds too close to real for comfort

Noooooooo

Oh hey, now I'm excited for these papers!

I worked at coffee shops for a few years and one of the joys of the job was memorizing regulars' orders to do exactly this thing. It's fun for everyone involved, I think :)

I like the balls argument! Will probably go that route next time

I have so many Chernoff arguments now! Thanks! #blessed

How're you holding up?

Nice, thanks!

Thank youuuuuu

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

The subspecies of CS theorists typically does, yeah

Marco gave me the remainder of his box when he graduated from UCSD, but now I know who to ask when I run out. Thanks!

Yessssss I got a lecture hall with sliding chalkboards, this rules

Nice, thanks for the tip!

I will not have to wait long 😂

Just wrote my first letter of recommendation for a student 😀. Anyone coming into my replies with, "just wait until the 100th," energy WILL BE BLOCKED, please just let me have this.
