The ROC curves of different AI methods and the typical visualization of attention weight. A The ROC curves for predicting ICU patients’ in-hospital mortality 48 h after admission based on different AI methods. B The typical heatmap for attention weight of variables and time points for the non-survival patient. C The typical heatmap for attention weight of variables and time points for the surviving patient.
