New preprint!

This is a hardcore technical paper on Thompson sampling - as a strategy for the so-called online learning game.

I think it's one of the most long-term important things I have ever worked on due to what it makes possible.

But that needs explaining - thread below!

I’m excited to announce that in July 2025 I will be joining @UWaterloo as an Assistant Professor in the Department of Statistics and Actuarial Science! Until then, I will continue at Princeton as a DataX Postdoc Fellow, working with Boris Hanin.

I have many exciting projects lined up to study the scaling limits of neural networks and their training dynamics, with some important practical implications on the horizon. Stay tuned!

[Jeffrey Negrea @jeffNegrea]

@roydanroy @ArnaudDoucet1 @wellingmax I think the analogy needed to make ``optimal scaling'' work is that each of your papers is an infinite product of block-iid sections.

Congratulations to Dr @HaghifamMahdi on a successful thesis defense at U of T!
🌟🔥🎉👏🔥🌟🎉

Next stop: Distinguished Postdoctoral Fellow at the Khoury College of Computer Sciences at @NorthEastern.

[Blair Bilodeau @blairbilodeau]

3.5 years after we started this project while visiting @the_IAS, it’s been accepted to the Annals of Statistics.

I won’t be at #JSM2023 but make sure to stop by Jeff’s session to hear about our work!

[Jeffrey Negrea @jeffNegrea]

Super excited that this work has been accepted for publication in AoS.

For those at #JSM2023, I'll be speaking about it in the session on Advances in Statistical Machine Learning, scheduled for Sunday 8/6/2023 2:00:00 PM.

I'm speaking first so don't be late 😉.

I'm _incredibly_ excited about this paper.

Deep insights for prompting, and for how models represent latent knowledge about the world. See the paper and check out @wzihao12's thread!

Some extra (more speculative) nuggets below:

[Zihao Wang @wzihao12]

Prompt engineering is a dark art. To understand limitations, we formalize "what the user intended" through latent concepts. Then we show direct model controls by algebraic operations on suitably chosen representations!https://t.co/kK4I38Jf76 w @ybnbxb @jeffNegrea @victorveitch

@miniapeur Who needs a VC? Just "pull yourself up by your bootstraps"!

@PhDemetri @finbarrtimbers something something purrr-ist

Congratulations to Dr. Jeffrey Negrea (@jeffNegrea) on the successful defense of his dissertation! No corrections. Superb job.

@kareem_carr Sort columns separately first

@roydanroy @Usman_skhan Influence by osmosis => coffee was spilled on them

[Jeffrey Negrea @jeffNegrea]

@roydanroy it expects labels to be all caps sometimes, and it seems safer to wrap \crefs in {} within titles. doing that and defining the label twice, once with all caps and works for me... dm me a mwe if not

[Jeffrey Negrea @jeffNegrea]

@trongthangpham @ccanonne_ I assume they are custom made using tikz or something. Not certain though.

[Jeffrey Negrea @jeffNegrea]

@ccanonne_ (but actually this is really well thought out notation that just looks confusing at first glance)

[Jeffrey Negrea @jeffNegrea]

@ccanonne_ numerical analysis: hold my beer
