LIBERO-Para: A Diagnostic Benchmark and Metrics for Paraphrase Robustness in VLA Models

arXiv:2603.28301v1 Announce Type: new Abstract: Vision-Language-Action (VLA) models achieve strong performance in robotic manipulation by leveraging pre-trained vision-language backbones. However, in downstream robotic settings, they are typically fine-tuned with limited data, leading to overfitting
