An Empirical Study and Open Testbed for Federated Fine-Tuning of Vision-Language-Action Models

Zhekai Duan, Kevin Ziyang Xie, Xinyu Tan +5

Adapting a pretrained Vision-Language-Action (VLA) model to a new robot, environment, or task requires demonstrations that are collected locally and often discarded. Federated lear…
