Figure 6. Baseline interpretability analysis of the standard ANN model. (A) SHAP summary plot illustrating the feature impact distribution for the pure data-driven ANN; (B) Global feature importance ranking. While the model identifies key descriptors, the ranking relies solely on statistical correlations within the training data; (C) SHAP dependence plot for the top-ranked feature. ANN: Artificial neural network; SHAP: SHapley Additive exPlanations; VEC: valence electron concentration.
