Prediction Explanation: Fermi 2

Feature importance and per-unit prediction explanations for the model.

Per-Unit Prediction Explanation

Why was this prediction made? Each bar shows how a feature pushed the prediction higher or lower compared to the fleet average.

When will the next refueling outage begin?
