Table 2 Statistical validation for correlation.
From: Machine learning-driven nonlinear analysis of inclusion effects in aluminium alloys
Metric | Value | Interpretation |
|---|---|---|
R² | 0.82 | Strong nonlinear correlation |
RMSE | 12 MPa | Model prediction error ± 12 MPa |
Curve Slope | −8 MPa/µm (0–5 μm), −4 MPa/µm (5–15 μm) | Nonlinear decay rate |
