@_rockt - congratulations on such an exciting @iclr_conf keynote! A case for world models as step to open ended agent learning, including robotics

[Katja Hofmann @katjahofmann]

@sandyasm @danqi_chen @iclr_conf can you respond to this?

[Katja Hofmann @katjahofmann]

Really enjoyed @danqi_chen‘s keynote at #ICLR2025 this morning. She made a great case for research on LM training on academic budgets with focus on model architectures, data quality and post training coupled with systematic benchmarking

[Luisa Zintgraf @luisa_zintgraf]

🎉 Our Meta-RL survey is now published in Foundations and Trends in Machine Learning! A deep dive into how agents can learn to learn 🤖🧠

Huge kudos to @jakeABeck & @ristovuorio for leading the charge, and to co-authors Evan Liu, Zheng Xiong, @chelseabfinn & @shimon8282!
