Amazing banquet tonight at #EurIPSConf !

🇪🇺✨ ELLIS Unit Milan at #EurIPS Alongside NeurIPS, several of our works will also be presented at EurIPS! Join us there to discover our contributions. We’re excited to share our work with the community! 🔍 Check out the list of our papers presented at EurIPS here 👇

I am at NeurIPS in San Diego this week presenting our paper “Instance-Dependent Regret Bounds for Nonstochastic Linear Partial Monitoring”. This is a joint work with my amazing collaborators, Dr. Khaled Eldowa and Prof. @NicoloCB arxiv.org/abs/2510.19158

A great day at the @ELLISforEurope Pre-NeurIPS Fest in Milan last week! 🎉 Researchers from Bicocca, Bocconi, Polimi and Unimi gathered to share research highlights, discuss the Unit’s vision, and present their latest work. Read more about the event here: ellismilan.eu/2025/11/21/ell…

If you’ll be in Copenhagen for the @ELLISforEurope Unconference + #EurIPS, don’t miss the #ELLIS Workshop on Interactive Learning & Interventional Representations on Dec 2! It covers current topics in RL, causality, and their intersection. More info: sites.google.com/view/ilir-work…

Reminder: tomorrow is the ELLIS Milan Pre-NeurIPS Fest Workshop 2025! Join us at the University of Bicocca for a full day of inspiring talks, posters, and discussion. More info & full program of the event: sites.google.com/unimib.it/pre-…

Fascinating invited talk by @NicoloCB on “Multiagent Online Learning” at #IBIS2025 yesterday. Loved the insights on how communication improves performance regret bounds. Great thanks to the audience as well for engaging Q&A session! 2日目もよろしくお願いします！

Proud to be in amazing company on SICOMP’s list of most cited papers...

EurIPS is coming! 📣 Mark your calendar for Dec. 2-7, 2025 in Copenhagen 📅 EurIPS is a community-organized conference where you can present accepted NeurIPS 2025 papers, endorsed by @NeurIPSConf and #NordicAIR and is co-developed by @ELLISforEurope eurips.cc

New Article: "Improved Regret Bounds for Bandits with Expert Advice" by Cesa-Bianchi, Eldowa, Esposito, and Olkhovskaya jair.org/index.php/jair…

How can we design algorithms that maximize social welfare, rather than profits? This paper merges multi-armed bandits and adversarial learning with optimal tax theory and welfare economics. @maxkasy @NicoloCB @Rcolomboni econometricsociety.org/publications/e…

@tverven Yeah! Congrats!!!

Hooray, I received a Vici grant from the Dutch science foundation! Heads up for current PhD students in learning theory: I will have two postdoc positions available in Amsterdam on "learning theory for interpretable/explainable AI" in the coming years. uva.nl/shared-content…

The math institute at Oberwolfach displays books authored by workshop participants for them to sign. Today I caught up with a long due signing...

🚨 Exciting news! The ELLIS Unit Milan is hosting ALT 2025 at @polimi in Milan on February 24-27, 2025. 🎉 Don’t miss this opportunity! 📅 Register now: eventbrite.com/e/alt-2025-tic… For more info: algorithmiclearningtheory.org/alt2025/ See you in Milan! 🇮🇹✨

@wellingmax True! And their end-of-the-year summaries of the most exciting discoveries in CS, math, physics and biology are just great!

Truly excellent piece on entropy. Source: Quanta Magazine search.app/ichMj5mCxENsWC…
