Figure 4

Feature importance derived from support vector machine model. This figure is the result of the DALEX package. The X-axis represents the loss in the area under the curve (AUC) calculated after randomly permuting the feature compared to the original AUC. The greater this loss, the higher the model’s importance of this feature. CCI, Charlson Comorbidity Index; APACHE II score, Acute Physiology and Chronic Health Evaluation II score; CRP C-reactive protein; MV, mechanical ventilation.
