We have the keynote speakers for RLC2026 now! Thrilled to welcome Rika Antonova, Sheila McIlraith, Marc G. Bellemare, Danijar Hafner, Balaraman Ravindran! Details: rl-conference.cc/index.html The RL community is coming together this August in Montréal, Québec, Canada. Hope you make it!

Applications for the global Google PhD Fellowship Program are open! Fellowships directly support grad students doing exceptional and innovative research in computer science and related fields as they pursue their PhD. Learn more and apply by April 30 at goo.gle/phdfellowship.

Exploring SigReg regularization for RL has been on my "todo when I have time" list for a while. While I haven't fully read this paper yet, it appears to do a fantastic thorough investigation, and it looks quite promising!

New paper 🚨 "Stable Deep Reinforcement Learning via Isotropic Gaussian Representations" Deep RL suffers from unstable training, representation collapse, and neuron dormancy. We show that a simple geometric insight, isotropic Gaussian representations, can fix this. Here's how 👇

In light of the ongoing conflict in the Middle East, RLC decided to remove the abstract deadline: rl-conference.cc/callforpaper... The only deadline is for the full paper: Mar 5(AOE) openreview.net/group?id=rl-... Affected folks may also contact the PCs to discuss deadline extensions before Mar 5.

RLC 2026 Call for Workshop is live on OpenReview! Submission deadline: Mar 12 (AoE). Full details here: rl-conference.cc/call_for_wor... @glenberseth.bsky.social @eugenevinitsky.bsky.social @twkillian.bsky.social @schaul.bsky.social @sologen.bsky.social @audurand.bsky.social @bradknox.bsky.social

It's been such a pleasure working with @caroline-wang.bsky.social the last few months. She is a fantastic researcher, engineer, & person, and I really hope we can work together again. Check out the paper that came out of her time with us, comparing strategic behavior of humans and LLMs!👇🏽

Hi RL Enthusiasts! RLC is coming to Montreal, Quebec, in the summer: Aug 16–19, 2026! Call for Papers is up now: Abstract: Mar 1 (AOE) Submission: Mar 5 (AOE) Excited to see what you’ve been up to - Submit your best work! rl-conference.cc/callforpaper... Please share widely!

Today's wordle made me feel warm. Wordle 1,646 2/6 ⬛🟨🟩⬛⬛ 🟩🟩🟩🟩🟩

Despite some of its flaws, OpenReview has had a tremendously positive impact on our research community. This is a great initiative! Join me, and many others, in donating to ensure OpenReview not only remains a positive force, but is able to improve.

This #NeurIPS2025 was tiring, but it was fantastic to connect with so many friends and colleagues! I was so busy I didn't get a chance to tweemote our papers at the conference, so I'll remedy that with this post-hoc thread: 👇🏾

Sixth, and last, #runconference at #NeurIPS2025 had the best turnout yet! Thanks to everyone who came out, until the next conference! The second picture is of those who stayed until the end 😅🏅 🤖🏃🏾👋🏾

Fifth #runconference at #NeurIPS2025 , good turnout again! Tomorrow is the last run (at least with me), so if you've had FOMO this week, you have one more chance! 🤖🏃🏾

Fourth #runconference at #NeurIPS2025 had the best turnout yet! Help us beat it tomorrow, same place, same time (follow tweet thread for details)! 🤖🏃🏾

Third #runconference at #NeurIPS2025 was great, including special guest @JeffDean ! Same place, same time, tomorrow morning if you want to join! 🤖🏃🏾 (I forgot to post yesterday's pic, so including it here)

. @roger-creus.bsky.social and @johanobandoc.bsky.social did an awesome job presenting our paper at the LatinX in AI workshop at #NeurIPS . If you missed it, come to our poster #310 on Friday 11am, exhibit hall C,D,E.

Join us tomorrow at #runconference for #NeurIPS2015, same time, same place (see quoted thread for details)! It was three of us this morning but I forgot to take a picture before we separated, so here's a selfie to prove we actually went out 🤭 Hope to see more of you tomorrow!

Just landed in San Diego for #NeurIPS2025 ! If anyone wants to join me for #runconference tomorrow, meet me at the pin at 7:00am. We'll play distance and pace by ear, based on who shows up See you then! 🤖🏃🏾 maps.app.goo.gl/W7fedHdpsrFn...

Today's wordle was received as a gift. Wordle 1,622 2/6 ⬛🟩🟩⬛⬛ 🟩🟩🟩🟩🟩

My lab is looking for new students who are very passionate about foundational models and planning/RL/robotics. Apply via Mila. I will also be at #NeurIPS to discuss research ideas and opportunities. See notes below for application advice.

🚨The Formalism-Implementation Gap in RL research🚨 Lots of progress in RL research over last 10 years, but too much performance-driven => overfitting to benchmarks (like the ALE). 1⃣ Let's advance science of RL 2⃣ Let's be explicit about how benchmarks map to formalism 1/X

Proud to announce that Meta-World+ was accepted to NeurIPs, Datasets and Benchmarks! Meta-World is a common benchmark for multi-task and meta-RL research! However, it was very difficult to do effective science with Meta-World as different versions produce different results.

🔊Simplicial Embeddings (SEMs) Improve Sample Efficiency in Actor-Critic Agents🔊 In our recent preprint we demonstrate that the use of well-structured representations (SEMs) can dramatically improve sample efficiency in RL agents. 1/X

Very excited to be able to talk about something I've been working on for a while now - we're working with Commonwealth Fusion Systems, IMO the leading fusion startup in the world, to take our work on AI and tokamaks and make it work at the frontier of fusion energy. deepmind.google/discover/blo...

Hello everyone 👋 Good news! 🚨 Our Game Theory & Multiagent Systems team at Google DeepMind is hiring! 🚨 .. and we have not one, but two open positions! One Research Scientist role and one Research Engineer role. 😁 Please repost and tell anyone who might be interested! Details in thread below 👇

this was a really great workshop at @rl-conference.bsky.social , and i enjoyed giving a talk and moderating a panel there. everything was recorded, so if you weren't able to join, you can watch it now, link below.

📢MARK YOUR CALENDARS!🗓️ The Summit of AI in Latin America (SALA, formerly RIIAA) is happening in Quito, Ecuador, March 9-12, 2026, at USFQ! Want to attend and apply for travel grants? Do so here before October 1st: forms.gle/PgYUQ2urGNTs... More details in thread 👇🏾🧵

Very happy this work got into #NeurIPS2025, it was a big effort that Reggie led, and I'm glad it was worth the work! We've already been using Meta world+ in a lot of our research, and so should you! Let's chat at #NeurIPS2025 !

Caught my 11yo reading this, I'm so proud.

want to help shape the future of AI in latin america? then don't miss out on @lasalaai.bsky.social next march! the past instances of this event have been truly fantastic, and i'm super pumped for the next one next year. don't miss out and apply today! hope to see you in quito!! ♥️🇪🇨

Software engineering isn't dead, it just smells funny.

Yesterday I did a 28.4k trail run and 1300m climb with some good friends (& colleagues). It was absolutely incredible! This was my first trail run, but now I think I'm hooked! #trailrunpostconference

Once again, I leave @rl-conference.bsky.social convinced that it's the best conference out there for RL researchers, such a great week! It was also so great getting the opportunity to see so many of my students shine while presenting and discussing their research!

Did the last #runconference @rl-conference.bsky.social this morning, fun as always. Until the next time (NeurIPS?)!

Was great listening to Turing award winner Rich Sutton tell us about his vision for the future of RL (and AI) @rl-conference.bsky.social !

Great talk by Peter Dayan @rl-conference.bsky.social exploring the "open marriage" between natural and engineered reinforcement learning.

Great #runconference @rl-conference.bsky.social today (even with a little rain), join for the last one tomorrow morning, 6:30am, meet at Garneau Lamp!

😁

today (thu) @rl-conference.bsky.social come see our paper "Optimistic critics can empower small actors" olya and dhruv will present the oral at 11:45am in the deep RL track (CCIS 1-430) and we'll present the poster (poster#8) 3-5:45pm come chat with us about asymmetric actor-critics!

Very honoured that our paper was granted an outstanding paper award for scientific understanding in RL during the @rl-conference.bsky.social banquet! @reggiemclean.bsky.social and Evangelos deserve the bulk of the credit, so congrats to them and all the other awards winners!

Super thought-provoking talk by Dale Schuurmans @rl-conference.bsky.social on LLMs and computation, and why value-based RL doesn't (or can't?) work for post-training.

Second #runconference today went well, join us tomorrow same place (Garneau Lamp), same time (6:30am)!
