The simplex algorithm is super efficient. 80 years of experience says it runs in linear time. Nobody can explain _why_ it is so fast.

We invented a new algorithm analysis framework to find out.

Beyond Smoothed Analysis: Analyzing the Simplex Method by the Book

Narrowing the gap between theory and practice is a longstanding goal of the algorithm analysis community. To further progress our understanding of how algorithms work in practice, we propose a new alg...

Is there a deeper rationale behind this trick?🤯 It turns the objective from a fraction to a quadratic for which the opt f can be easily derived (which doesn't seem to be the case for the original objective).

Yihan Zhang @yihanzhang.bsky.social · Feb 12

Actually I realized that I never received the hard copies. Am I supposed to reply to the publisher’s email with my address? 😅

I want to explain in down-to-earth terms what this paper is about, since it ultimately boils down to what I think are some really concrete and fundamental questions. 1/n

I find this a really useful model to gain intuition into the behavior of optimization algorithms in high-dimensional overparametrized landscapes, as the ones arising in modern machine learning.

Past work has characterized the functions learned by neural networks: arxiv.org/pdf/1910.01635, arxiv.org/abs/1902.05040, arxiv.org/abs/2109.12960, arxiv.org/abs/2105.03361. But it turns out multi-task training produces strikingly different solutions! Adding tasks produces “kernel-like” solutions.

Our monograph on "Codes for Adversaries: Between Worst-Case and Average-Case Jamming" (joint work with Bikash Kumar Dey, Sidharth Jaggi, Michael Langberg, and Yihan Zhang) is now published!

Writing this has been a great experience and I'm so excited!

Overleaf now incorporates an AI assistant, as of this morning. It is opt-out, not opt-in.

I have very mixed feelings about this: and by "mixed", I mean ranging from annoyance to anger.

Agreed!

A useful tip: I have recently started using the \citeauthor command for this purpose, and I find it really convenient.

Clément Canonne @ccanonne.github.io · Nov 30

Reminder: if there are 3 authors or fewer, name them all, no "et al."

Actually, try to name all authors if you can, at least the first time you mention the work. And *especially" if the author ordering is alphabetical! "Aaaaa et al." gets old quickly for X, Y, and Z.

It's looking like all the open problems I have thought about in the last 10 years are now solved (or in some cases on the verge of being solved)? Latest case in point this beautiful new paper: arxiv.org/abs/2411.18614 . I'm glad we (humans) got all this results just in time!

Optimal root recovery for uniform attachment trees and $d$-regular growing trees

We consider root-finding algorithms for random rooted trees grown by uniform attachment. Given an unlabeled copy of the tree and a target accuracy $\varepsilon > 0$, such an algorithm outputs a set of...
