Ablation study on decay blending of Random Forest model for SPN01499. Intermediate blending (α = 0.2–0.4) produces smoother, physically plausible demand decline compared with unblended (α = 0.0) or fully decayed (α = 1.0) predictions. Ablation study on decay blending of XGBoost model for SPN01499 with horizon-wise projection.
