Can you solve MARL tasks without conditioning the policy on the observation? In our new paper we investigate the popular StarCraft micromanagement benchmark SMAC and discover that most scenarios do not require the observation to be used! [1/N]

Hindsight Experience Replay has become the ubiquitous method for goal-conditioned reinforcement learning, but leaves open the question of which goal to relabel with.

In this work, accepted at ICML, we propose instead simply Learning Everything All at Once (LEO).

Very excited to share that Reflection is partnering with Shinsegae Group to build a 250-megawatt AI factory for South Korea.

I believe this is a sign of things to come and it's a privilege to be part of it.

Reflection is partnering with Shinsegae Group to build a 250-megawatt sovereign AI factory for the Republic of Korea.

Open intelligence. Built on trust between allies. Owned by the nations that need it most.

The future of sovereign AI. Read more in the @WSJ.

@reflection_ai @WSJ Super cool to be part of this mission!

[Ben Ellis @benjamin_ellis3]

@MishaLaskin Super exciting!

[Misha Laskin @MishaLaskin]

AGI is in its first stages of take-off.

Every country is realizing that AI sovereignty is existential, which requires open models.

We’ve signed a deal with Shinsegae Group to build South Korea’s sovereign cloud on a US open model built by Reflection.

More to come.

My PhD thesis is out 🥳🎓

How do LLMs, trained on trillions of tokens, reason?
Can they generalise beyond their training data or are they constrained by what they've seen before?

My takeaway: they can generalise beyond training in interesting ways, showing genuine reasoning

[yobibyte @y0b1byte]

I am looking for an intern to do a research project on RL posttraining of LLMs. If you are PhD student and would like to work with me for several months pushing the efficiency of RL systems, send me an email with the [efficient_rl_internship] subject. Friends, please, retweet.

[Ben Ellis @benjamin_ellis3]

@_ghorbani @psanfernandes @reflection_ai Excited to have you on board 🚀

Hello World: I am reviewing Phd applications and the level of talent is amazing. Sadly, the funding situation is extremely challenging.
SO: If you'd like to gift someone brilliant literally the opportunity of their lifetime and sponsor their Phd in my group please let me know 🙏
