viva passed with minor corrections! Thanks to @MichaelD1729 and @ale_suglia for serving as my examiners and to my wonderful advisors @dabelcs and Chris Lucas for the incredible mentorship and support over these past years!

Attending #ICML and interested in World Models? PERSIST models the world within an explicit 3D latent representation. Come by to discover the unique capabilities this unlocks! 📍 Poster 2715 • Thursday • 2:30pm #ICML2026 #WorldModels #GenerativeAI #3DGeneration
David Abel retweeted
This week's #PaperILike is "General agents contain world models" (Richens et al., ICML 2025). Brought to my attn by @dabelcs 's beautiful philosophy-laden talk at ICAPS. The explicit construction of a transition model from a policy is cool (Alg 1). PDF: arxiv.org/abs/2506.01622
David Abel retweeted
Model-free agents learn to maximise reward without modelling the environment. Right? In recent work, we challenge this narrative by proving that agents, trained on a sufficiently rich set of goals, encode a unique and accurate world model in their value functions. 1/

We are starting a new, nonprofit alignment organization, ⊢ Sequent Research, bringing together researchers previously on UK AISI’s Alignment Team, Timaeus, and elsewhere to research how to align superintelligence. We are hiring! 🧵

Just published in @PNASNews, we resolve a 50-year-old riddle from Richard Feynman's handwritten notes, prove and generalize it, and run a large-scale human study to reveal near-optimal heuristics in sequential decision problems: doi.org/10.1073/pnas.2…
David Abel retweeted
"Imperfect World Models are Exploitable" World models can look accurate, but still rank policies incorrectly, saying policy A is better than policy B when the real environment says the reverse. This paper formalizes that failure as model exploitation and proves it is basically unavoidable for any nontrivial, nonequivalent world model on broad policy sets. It also connects this to reward hacking and derives a safe horizon showing how model error compounds with planning depth.

Reminder that the deadline for the Finding the Frame workshop @RL_Conference is coming up on May 22 AoE ⏰ We're excited to read your submissions reflecting on the philosophy, practice, and formalisms of reinforcement learning! 🔗 More details: sites.google.com/view/findingth…
@Dr_Atoosa @GoogleDeepMind Congrats Atoosa!
@shimon8282 @whi_rl Congratulations Shimon! Exciting news, welcome to DeepMind 🙂

Really excited to present our recent work at #ICLR2026 this week! We discover highly coordinated joint behaviours and integrate them into the skill sets of MARL agents, accelerating the search for effective joint strategies in downstream tasks.🧵 Paper: raulsteleac.github.io/iaro
