DiVeR method enhances robot action selection in VLA policies

By PulseAugur Editorial · [1 sources] ·

Researchers have developed DiVeR, a novel approach to improve Vision-Language-Action (VLA) policies by focusing on decision-critical states during test-time scaling. This method addresses the high cost of robotic data by reweighting the learning process towards states where action selection has the most significant impact on task success. DiVeR estimates this decision criticality based on the dispersion of sampled action representations, without needing step-level annotations. Experiments across simulated environments like LIBERO and RoboCasa, as well as on a real-world Franka Research 3 robot, demonstrate that DiVeR effectively enhances task success with minimal additional inference overhead.

    DiVeR: Decision-Critical Verifier Learning for VLA Test-Time Scaling

    Scaling robot data and model capacity has improved Vision-Language-Action (VLA) policies, but further progress is constrained by the high cost of robotic data. Verifier-guided test-time scaling offers an efficient alternative by sampling multiple action candidates and selecting t…
