World models are key for developing adaptive agents. In our #ICLR2024 spotlight we present THICK: an algorithm to learn hierarchical world models with versatile temporal abstractions. And we show how they can enhance model-based RL or planning… 📜 openreview.net/forum?id=TjCDN… 1/🧵

🤖 🌍 We have extended the submission to our CoRL (@corl_conf) workshop about Robot World Models for one more week! Use your chance to submit! 🌏🤖 ❗️Both 1-page abstracts of published works and 4-page novel works in progress are welcome! 📡 Details: simulatingrobotworlds.github.io/submit.html

Introducing DINOv3 🦕🦕🦕 A SotA-enabling vision foundation model, trained with pure self-supervised learning (SSL) at scale. High quality dense features, combining unprecedented semantic and geometric scene understanding. Three reasons why this matters…

Are you working on real-to-sim, sim-to-real, learning world models, or using physics-based simulators? There are two weeks left until the submission deadline for our CoRL workshop, Learning to Simulate Robot Worlds. More details here: 🔗simulatingrobotworlds.github.io/submit.html

🚀 We’re excited to announce our #CoRL2025 workshop: Learning to Simulate Robot Worlds Spanning high-fidelity simulators, digital twins, and learned world models - our goal is to unite communities to push robot learning forward 🤖🌐 🔗 simulatingrobotworlds.github.io 🧵🧵🧵

Reframing attention as an RL problem for causal discovery AI models like GNNs & Transformers can struggle with dynamic causal reasoning. Our work introduces the Causal Process Model (CPM), which reframes attention as an RL problem. Agents dynamically build sparse causal graphs.

@svlevine was just presenting in the Exploration in AI @ #ICML2025 and promoted that exploration needs to be grounded, and that VLMs are a good source ;-) Check our paper below 👇

Zero-shot imitation from just a single sparse demonstration is hard. Goal-conditioned methods tend to “greedily" move from one state to the next and lose the big picture. We're presenting an alternative approach on Tuesday at #ICML2025. (1/3)

When multiple tasks need improvements, fine-tuning a generalist policy becomes tricky. How do we allocate a demonstration budget across a set of tasks of varied difficulty and familiarity? We are presenting a possible solution at ICML on Wednesday! (1/3)

✨Introducing SENSEI✨ We bring semantically meaningful exploration to model-based RL using VLMs. With intrinsic rewards for novel yet useful behaviors, SENSEI showcases strong exploration in MiniHack, Pokémon Red & Robodesk. Accepted at ICML 2025🎉 Joint work with @cgumbsch 🧵

How to represent dynamic real-world data both consistently and efficiently, while reflecting the compositional object-centric structure of the world? Contrast your slots! ...with our new SlotContrast method(🚀#CVPR2025 Oral🚀)! 🌐website: slotcontrast.github.io 🧵🧵🧵 1/n

#Context plays a critical role not only in interpreting language but many other cognitive processes. In a new paper, we propose that context-sensitivity is a core feature of human memory that enables flexible planning, #generalization, and decision making doi.org/10.1016/j.neub…

Were you ever wondering why there are little-to-no diverse offline imitation learning algorithms 🤔? Then we've got something 4 you! Our paper, "Offline Diversity Maximization under Imitation Constraints" is being presented today at RLC2024 🎇! 🧵 rlj.cs.umass.edu/2024/papers/Pa…

🚨We're back!🚨 Excited to announce The 2nd IMOL Workshop at #neurips2024! Send us your 📜newest work📜on learning & exploration in artificial and biological agents. #CFP at imol-workshop.github.io/pages/call/ 🔄Please share widely & stay tuned for more programming announcements!

Tired of causally confused agents when learning from offline datasets? We propose 🚣🏼‍♀️CAIAC🚣🏼‍♀️, a method for counterfactual data augmentation to improve the robustness of offline learning agents against extreme distributional shifts at test time. 🧵

🚨Introducing GenRL! An embodied AI agent that learns multimodal foundation world models 🌍 By connecting the multimodal knowledge of foundation models with the embodied knowledge of world models for RL, GenRL enables turning vision and language prompts into actions!

THICK PlaNet 🪐: We can also plan directly with our model. In THICK PlaNet we first plan on the high level with MCTS and then we search for low-level actions to follow this plan. This is useful for long-horizon or hierarchical tasks and sparse rewards. 7/8
