RobustRLlib: A Unified Library and Benchmark for Robust Reinforcement Learning Algorithms

Read the original on arXiv AI →

RobustRLlib is a unified library and benchmark that consolidates 17 robust reinforcement learning algorithms, providing a single interface to improve reusability. It includes an evaluation platform covering diverse real‑world shifts and advanced tasks such as humanoid and vision‑language‑action scenarios. Systematic tests across 273 perturbation configurations map the current capabilities of robust RL methods, highlighting both effective areas and remaining robustness gaps.

HAF: Adapting Generalist VLAs to Humanoid Whole-Body Loco-manipulation via Hierarchical Action Flow and Spectral Latent RL

arXiv:2608. 16837v1 Announce Type: cross Abstract: Humanoid robots hold great promise as general-purpose agents in human-centered environments, yet generalist vision-language-action (VLA) foundation models are not readily applicable to humanoid whole-body loco-manipulation.
