We depicted the SHAP summary plot of RF using the best 20 features in the prediction model to determine probably the most critical options that influenced the prediction model (Figure five). A feature having a greater SHAP value indicates a greater likelihood of NICU mortality based on the prediction model. The red and blue plots within the SHAP Piceatannol Technical Information represent larger and smaller values, respectively, which recommend that rising values or decreasing values will boost or decrease the predicted probability of mortality, respectively. The SHAP is consistent with the perfect performance of our RF model.Biomedicines 2021, x FOR Biomedicines 2021, 9,9, 1377 PEER REVIEW8 14 9 of ofFigure four. Value matrix plot four.
