Presenting at 2022 Workshop on FL and Analytics organized by Google
I’m taking part in the 2022 Workshop on Federated Learning and Analytics on 9 and 10 November. I am giving a talk about our work on Asynchronous SGD in the mini-workshop on Federated Systems at Scale on 9 November.
I'm giving a talk at Institut Henri Poincaré
I’m giving a talk at Séminaire Parisien d’Optimisation on 10 October. I will be presenting my work on second-order optimization, including the Super-Universal Newton paper.
Visiting Sebastian Stich in Germany
Between 22 June and 28 June, I visited Sebastian Stich, who works at CISPA Helmholtz Center for Information Security near Saarbrücken in Germany. We discusses new ways to solve nonconvex problems, and we already have some interesting results. Sebastian is also looking for PhD students, so if you or someone you know is looking for a good supervisor working on optimization, Sebastian should be the first person to contact!
New paper: Asynchronous SGD with arbitrary delays
My first ever optimization project was an ICML paper about an asynchronous gradient method. At the time, I was quite confused by the fact that no matter what I was doing, Asynchronous gradient descent still converged. Five years later, I can finally give an answer: Because Asynchronous SGD doesn’t care about the delays, which we proved in https://arxiv.org/abs/2206.07638 our new paper. For a short summary, you can read my twitter thread about the paper or check my slides.
I'm at attending SICO conference 12-15 June

In a few days, I am travelling to Autrans, Vercors near Grenoble for the SICO conference dedicated to the 60th birthday of Anatoli Juditsky. The conference will feature a number of speakers working on optimization and statistics. As I did my master’s thesis at the University of Grenoble, I’m really happy to go there again after having been away for almost 5 years.

On the last day of the conference, I will give a talk about a new paper on Asynchronous SGD. The work that I will present is also going to appear online quite soon.

2 papers accepted to ICML

Two of my papers got accepted for presentation at ICML:

The first of these two papers was a first-time submission and the latter was a resubmission. Earlier, we opted in to release online the reviews for the Prox RR paper from NeurIPS 2021, so the ICML reviewers could see (if they searched) that our work was previously rejected. Nevertheless, it was recommended for acceptance.
Although I’m happy about my works, I feel there is still a lot of changed required to fix the reviewing process. One thing that I’m personally waiting for is that every conference would use OpenReview instead of CMT. OpenReview give the opportunity to write individual responses to the reviewers and supports LaTeX in the editor, which are amazing things.
If your paper did not get accepted, don’t take it as a strong evidence that your work is not appreciated, it often happens to high-quality works. A good example of this is the recent revelation by Mark Schmidt on Twitter that their famous SAG paper was rejected from ICML 2012.
