SCAPE is a scenario‑conditioned simulation‑augmented policy evaluation framework that predicts real‑world policy performance for specific scenarios using limited paired simulation‑and‑real samples and extensive simulation rollouts. It corrects sim‑to‑real bias in simulation labels before training the prediction model and calibrates prediction uncertainty via conformal prediction. Experiments on autonomous driving and quadruped velocity tracking show SCAPE reduces scenario‑level prediction error, improves testing sample efficiency, narrows calibrated prediction intervals, and generalizes better to out‑of‑distribution scenarios, enabling fine‑grained deployment strategies.

The paper introduces a joint simulation–experiment training framework that treats simulation and experimental data as separate objectives in a multi‑objective learning problem. Experiments on four fluid systems show that joint training outperforms both simulation‑only and experiment‑only baselines, as well as the conventional simulation‑to‑experiment fine‑tuning approach, by achieving a more balanced performance across domains and better retaining simulation‑specific information. The authors demonstrate that joint training preserves simulation‑only fields that are absent from experimental measurements, leading to improved overall predictive accuracy.
