Leveraging Offline Supervision for Efficient and Generalizable Reinforcement Learning in Large-Scale Vision-Language-Action Models

Dmitriy Poyarkov, Aleksei Staroverov, Aleksandr I. Panov

It is commonly observed that online reinforcement learning (RL) produces better-performing strategies than offline methods across a broad range of performance measures. In particular, RL-trained policies exhibit stronger out-of-distribution (OOD) behavior, where models trained on…

VLA Grounder: Language-Conditioning Space Optimization for Black-Box VLA Models

Damir Shodiev, Aleksei Staroverov, Nikita Kachaev, Alexey K. Kovalev, Aleksandr I. Panov

Vision-Language-Action (VLA) models are commonly treated as end-to-end action policies conditioned on natural-language task descriptions. In practice, however, their behavior often depends sharply on how the instruction is phrased, suggesting that language is not merely a task la…
