We are starting the @arlet_workshop! We have an amazing line-up today

[RL3 @ Polimi @rl3polimi]

🚀 Congratulations to @marcomussi95 for winning the prestigious Dimitris N. Chorafas Prize for his PhD thesis “Online Learning Methods for Pricing and Advertising.” A remarkable achievement! 🎉

[RL3 @ Polimi @rl3polimi]

At #EWRL2025 in Tübingen, @alberto_metelli and @papinimat presented their contributed talks - great insights on inverse RL and policy gradients shared with the community!

[ARLET @arlet_workshop]

We've extended the deadline for our workshop's calls for papers/ideas! Submit your work by August 29 AoE. Instructions on the website: https://t.co/j7YBIHen0Q

🕚 Thu 17 Jul, 11:00 AM–1:30 PM PDT

[RL3 @ Polimi @rl3polimi]

@vincenz94, @RiccZamboni and @mirco_mutti will give an original take on how to make the best of parallel data collection for RL, how to enforce behavioral diversity and what this leads to in downstream tasks.
