Researchers introduce ASH, an agentic system that learns embodied policies from unlabeled internet video without reward shaping or expert demonstration. Through a self-improvement loop using Inverse Dynamics Models, ASH achieves sustained progression on long-horizon tasks in Pokemon Emerald and Legend of Zelda, significantly outperforming baseline approaches.
Researchers present VERA, a decoupled approach to robot control that separates video prediction from action execution using inverse dynamics models. Rather than fine-tuning video models with action labels, the method keeps the video planner unchanged and trains embodiment-specific models to translate predicted frames into robot actions, enabling zero-shot cross-embodiment generalization.
Researchers demonstrate that vision-language models (VLMs) can predict future image states by first learning inverse dynamics (identifying actions from frame pairs), then using this capability to bootstrap forward prediction through synthetic data annotation and inference-time verification. The approach achieves competitive results with specialized image editing models on the Aurora-Bench benchmark.
Researchers provide theoretical and empirical evidence that Predictive Inverse Dynamics Models (PIDM) outperform traditional Behavior Cloning in offline imitation learning by introducing a bias-variance tradeoff. PIDM requires significantly fewer expert demonstrations—up to 5x fewer in 2D tasks and 66% fewer in complex 3D environments—while maintaining comparable performance, offering practical advantages for training AI systems with limited data.
The article discusses research on transferring AI models from simulation environments to real-world applications through deep inverse dynamics modeling. This approach aims to bridge the sim-to-real gap in robotics and AI systems by learning how to map actions to outcomes in physical environments.
