New paper out! Together with my postdoc advisors @esoubies.bsky.social and Cédric Févotte :) We study the optimization landscape of L0-Bregman relaxations, which naturally arise when one optimizes non-quadratic fidelity terms coupled with the L0-norm. 1/n

Merry Christmas everyone!

Thrilled to be co-organizing NeurIPS in Paris at @sorbonne-universite.fr next week! 📑 100 papers from NeurIPS 2024. Nearly twice as many as in 2023! 🧑‍🎓 over 300 registered participants ✅ a local and sustainable alternative to flying to Vancouver. More info: neuripsinparis.github.io/neurips2024p...

Our paper "Mean robust optimization" has been accepted to Mathematical Programming: https://buff.ly/3B3VpIG 📰 Arxiv (longer version): https://buff.ly/3CT4aWD 👩‍💻 Code: https://buff.ly/3ATqAXh w/ Irina Wang, Cole Becker, and Bart van Parys A thread 🧵 (1/7)👇

My first tweet is going to be rather philosophical: the amount of cultural inputs we receive just because of being in an academic environment is huge. And we should be thankful for that.

Se acabó. Fue un placer, un dolor, un orgullo. Y "La última" casi una catarsis, porque el odio y la mentira intoxican si pasas mucho tiempo cerca. Sirvió, claro que sirvió. No hay más que ver las reacciones histéricas que generaba. Gracias! elpais.com/opinion/2024... ✨ ❤️
