MotionPyramid: Hierarchical Motion Representation and Residual Interfaces

MotionPyramid introduces a hierarchical action representation for humanoid control that learns motion structure from data, organizing behaviors across temporal scales from immediate motor commands to complex skills. The system uses frozen pretrained hierarchies as reusable action interfaces for reinforcement learning, with residual interfaces allowing policies to blend coarse and fine-grained control, demonstrating that motion can be organized like perceptual hierarchies.

When to Re-Commit: Temporal Abstraction Discovery for Long-Horizon Vision-Language Reasoning

Researchers introduce a learnable approach to commitment depth—the number of primitive actions executed before replanning—in vision-language models for long-horizon reasoning. Their adaptive policy outperforms fixed-depth baselines and surpasses GPT-4.5 and Claude Sonnet on puzzle-solving tasks, achieving higher solve rates with fewer actions.
