Heatmap of scaled SHAP values by ICD-10 chapter IX code for the version 2 neural net model. The value of each cell is calculated as the mean of the absolute SHAP values across all admissions. Values are scaled by ICD-10 code and can therefore be compared empirically as a ranking across ICD-10 codes where red indicates highest feature importance to the model, and blue indicates lowest feature importance to model. All absolute mean SHAP values for versions 1 and 2 neural nets are reported in supplementary Table 5
