arXiv:2606.00269v1 Announce Type: new Abstract: Vision-Language-Action (VLA) models can be steered at test time by intervening on semantically meaningful internal directions, but existing methods use a fixed steering coefficient, effectively operating in open loop. This is poorly suited to embodied control, where task state and concept error evolve over time, often causing overcorrection, oscillation, and reduced task success, especially for temporal behaviors such as speed and smoothness. We propose CTRL-STEER, a closed-loop framework that replaces static intervention strength with adaptive,
The increasing sophistication of AI models, particularly in embodied AI, necessitates more robust control mechanisms to overcome limitations of open-loop systems in dynamic environments.
This development addresses a critical challenge in embodied AI by enabling adaptive, real-time control, which is essential for safely and effectively deploying AI in physical world applications.
The shift from fixed-coefficient to closed-loop neural activation control in VLA models introduces adaptive steering, mitigating overcorrection and improving performance in complex, evolving tasks.
