Existing robot policies based on learned visual embeddings lack explicit structure and are sensitive to visual distractions. Thus, the representations that drive their behaviour are often opaque, making their decision-making process difficult to interpret.
The paper introduces RACE, a rollout‑free metric for selecting robot policy checkpoints that uses held‑out successful trajectories to calibrate action deviations against state‑conditional thresholds. By aggregating these calibrated scores with a running product, RACE reduces the influence of later reference predictions when early deviations occur, and averages the cumulative scores over time and across trajectories to produce a checkpoint score. Experiments in simulation and on real robots show that RACE outperforms baseline methods and its rankings correlate with deployment success across various policy backbones and tasks.

The paper introduces a method for quantifying epistemic uncertainty in flow‑matching based generalist robot policies, such as vision‑language‑action models and world‑action models. By measuring velocity‑field disagreement across a small ensemble, the authors obtain better‑calibrated uncertainty estimates that can detect deployment failures and guide active fine‑tuning. Their SAVE approach reduces the need for expert demonstrations, improving real‑world task success from 39 % to 47 % while maintaining a fixed demonstration budget.
