Interpretability of the model. (A) SHAP diagram. Each point represents a sample. The redder the color of the point, the larger the value of the variable, and the bluer the red, the smaller the value of the variable. The larger the ordinate of the point, the more likely the outcome is to be positive. (B) Importance ranking of key variables. The abscissa is the absolute value of the SHAP value, and the ordinate is the key variable. (C) The samples with a positive outcome. Red indicates a positive contribution to a positive outcome, and blue indicates a negative contribution to a positive outcome. The length of the bar indicates the size of the contribution. The longer the bar, the greater the contribution to the outcome. (D) The samples with negative outcome.
