When Instructions Retrieve Trajectories: Diagnosing and Mitigating Generalization Failures in VLA Models
Hung-Jen Chen, Yu-Hsun Hou, Yan-Hong Chen +4
Vision-language-action (VLA) models can exceed 90% success on in-distribution tasks and withstand nuisance changes that preserve the required action, yet fail under counterfactual…

Inductive Visual Logic for Few-Shot Out-Of-Distribution Adaptation in VLMs
Hung-Jen Chen, Yu-Heng Ho, Ting-Yao Huang +4
Generative vision-language models (VLMs) such as Qwen-VL and LLaVA achieve strong zero-shot performance on tasks overlapping with their pretraining distribution, yet fail on specia…
