Balancing Signal and Variance: Adaptive Offline RL Post-Training for VLA Flow Models

AAAI 2026technical

Vision-Language-Action (VLA) models based on flow matching have shown excellent performance in general-purpose robotic manipulation tasks. However, the action accuracy of these models on complex downstream tasks is unsatisfactory. One important reason is that these models rely solely on the post-tra

ReinboT: Amplifying Robot Visual-Language Manipulation with Reinforcement Learning

ICML 2025poster

Vision-Language-Action (VLA) models have shown great potential in general robotic decision-making tasks via imitation learning. However, the variable quality of training data often constrains the performance of these models. On the other hand, offline Reinforcement Learning (RL) excels at learning r…

Feature Enhanced Projection Network for Zero-shot Semantic Segmentation

ICRA 2021poster

In environmental perception of autonomous driving, zero-shot semantic segmentation that can make prediction of new categories without using any labeled training samples is considered as a challenging task. One key step in this task is to transfer knowledge across categories via auxiliary semantic wo…
