Fig 4. Personalized attention maps for three patients whose ICU courses were positive for myocardial ischemia, sepsis, and vancomycin.

Normalized input features in (A) are fed to the attention mechanism whose activations are visualized in (B). Ground truth labels and predictions for all target endpoints are labeled in (C). The days preceding the day of the ICU event, features with the highest time-relative activation on that day were identified in (D). The attention mechanism on the day of MI revealed a focus on nitroglycerin administration. For sepsis, administration of ranitidine and ceftriaxone were highly attended to in the days preceding the ICU event. Finally, in the case of vancomycin, the model attended heavily to labetalol, phenylepherine, and cefepime leading up to vancomycin requirement.
