Figure 6. Model validation: (A) SHAP value distributions for key features of the stacking model. The data points represent individual alloy samples, with each point color-coded according to the magnitude of the relevant feature. Positive SHAP values indicate that the feature increases the yield strength, while negative SHAP values suggest a decrease in yield strength due to the feature; (B) SHAP dependence scatter plot and ALE plot for single-feature δ and K; (C) 3D partial dependence graph of interaction feature [K, G]. SHAP: SHapley Additive exPlanations; ALE: accumulated local effect.
