I am pleased to share a review of my book "A course in reinforcement learning" (2nd edition) 4m4.it/collections/fk… This is the textbook for my RL course at ASU (free PDF at web.mit.edu/dimitrib/www/h…) #reinforcementlearning #machinelearning

Today I’m becoming a PhD—this time from Wharton (UPenn). I’m deeply grateful to everyone who supported me, especially my committee: Dean Knox, Jonathan Mummolo , Hamsa Bastani, and Eric Tchetgen Tchetgen.

So I've been messing around with this and LLMs. The quality of Mathlib + AI is getting to the point where mathematicians with *minimal* knowledge of Lean should be able to (with AI assistance) *state* (and themselves verify that the statement has the correct mathematical

Peter Lax's pragmatic approach to solving differential equations was influential across fields ranging from weather forecasting to starting nuclear chain reactions. go.nature.com/3SMubvA

You don't _need_ a PhD (or any qualification) to do almost anything. A PhD is a rare opportunity to grow as an independent thinker in an academic environment, rather than immediately becoming a gear in a corporate agenda. It's definitely not for everyone!

Finally, a good modern book on causality for ML: causalai-book.net by Elias Bareinboim. This looks like a worthy successor to the ground breaking book by Judea Pearl which I read in grad school. (h/t Joshua Safyan for the ref).

1998: Cult of the Dead Cow (cDc) debuted the program Back Orifice at DEF CON 6. The controversial remote system administration tool was written by Sir Dystic. Its successor, Back Orifice 2000 (BO2k) was released a year later at DEF CON 7.

The free exchange of ideas and the tolerance of those with whom we disagree is essential to the working of a liberal democracy. The shooting of Charlie Kirk in Utah is horrifying, and such political violence should have no role in America.

How should you use forecasts f:X->R^d to make decisions? It depends what properties they have. If they are fully calibrated (E[y | f(x) = p] = p), then you should be maximally agressive and act as if they are correct --- i.e. play argmax_a E_{o ~ f(x)}[u(a,o)]. On the other hand

Hi everyone! I am happy to share this note titled "Difference-in-Differences with Binarized Treatments: A Cautionary Tale". I study the common practice in DiD settings of recoding a multi-valued treatment into a binary indicator. I hope you enjoy it! dropbox.com/scl/fi/491xidv…

I crossed an interesting threshold yesterday, which I think many other mathematicians have been crossing recently as well. In the middle of trying to prove a result, I identified a statement that looked true and that would, if true, be useful to me. 1/3
