Attributing Preprocessing Invariance in Spectral Foundation Models

This work proposes a normalization-only attribution control: compare the encoder against its normalization before interpreting transfer as learned invariance, and confirms invariance develops only when variation reaches the encoder past normalization.

FWBC-VLA: Force-Aware Whole-Body Compensation for Contact-Rich Loco-Manipulation

The FWBC-VLA is proposed, a force-aware framework that bridges task-level VLA action generation and low-level whole-body compensation control for wheeled-legged robots and demonstrates the effectiveness of the FWBC-VLA in contact-rich loco-manipulation.

DECOWAM: Decoupled Whole-Body World-Action Model for Legged Mobile Manipulation

DECOWAM is introduced, a whole-body world-action model that separates camera ego-motion from base and arm actions through dedicated conditional interfaces and shows that embodiment-aware factorization can support parameter-efficient joint visual prediction and whole-body control under moving viewpoints.
