The "decoupling of information and energy" is a major point of divergence between biological and artificial computers. Brains are efficient, modern AI isn't. And energy consumption is the biggest bottleneck in scaling AI (you can't hallucinate electrons into existence). To address this we need an "energy-aware theory of computation." And this new preprint is an attempt to address this. [1/11] 🧵

Newton gave force, inertia, and motion precise mathematical definitions. This unlocked centuries of progress in mechanics. Turing did it for "computation," and Shannon for "information." Today, "agency" still feels a bit like "computation" before Turing: everybody uses the word, but there is no widely accepted precise definition. @dabelcs argue that RL needs to take this problem more seriously.

PERSIST is a world model that ditches pixel-based histories for a 3D world state. Instead of searching through an ever-growing sequence of past pixel observations, PERSIST retrieves spatial information from a dynamically evolving 3D representation. This change improves the spatial memory, 3D consistency, and long-horizon stability of the model, enabling interactive experiences within coherent and evolving 3D worlds. #MachineLearning #WorldModels #GenerativeAI #3DComputerVision #ComputerVision #Genie3 #AI

Assembling a team at DeepMind in London. Scaling up RL for post-training is working, but right now it's still mostly hacks and dark arts (pretraining circa 2019). Pre-training wasn't always scaling laws and log-log plots; someone had to find the simplicity. We aim to do the same. If you're interested in doing things right in a research-first environment that scales all the way, please apply: job-boards.greenhouse.io/deepmind/jobs/…

This is a very thoughtful paper They give a careful construction of an agent that is embedded in its environment: go talk to Alex!

@giffmana MDP is the worst thing about RL, beating the 'starting-from-scratch' every time. That's why I liked this paper arxiv.org/abs/2407.10583

Thrilled to present HyperMARL at #NeurIPS2025 in San Diego next week! 🚀 (Amos will present at @EurIPSConf too.) TL;DR: Coupling obs and agent IDs can hurt perf in MARL. Agent-conditioned hypernets cleanly decouple grads and enable specialisation. 📜: arxiv.org/abs/2412.04233

Kale-ab Tessera@KaliTessera

📜🤖 Can a shared multi-agent RL policy support both specialised & homogeneous team behaviours -- without changing the learning objective, requiring preset diversity levels or sequential updates? Our preprint “HyperMARL: Adaptive Hypernetworks for Multi-Agent RL” explores this!
