Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| add time-aware decay mechanism to GRU (ablation) | GRU · MIMIC-III in-hospital mortality | AUC: 0.883 -> 0.893 | Helped |
| add unreliability-aware attention (ablation) | T-GRU · MIMIC-III in-hospital mortality | AUC: 0.893 -> 0.913 | Helped |
| add symptom-aware attention on top of unreliability-aware (ablation) | T-GRU+u · MIMIC-III in-hospital mortality | AUC: 0.913 -> 0.919 | Helped |
| add symptom-aware attention (ablation) | T-GRU-raw · MIMIC-III in-hospital mortality | AUC: 0.889 -> 0.897 | Helped |
| model imputed (augmented) records instead of raw records (ablation) | T-GRU · eICU in-hospital mortality (1 day window) | AUC: 0.768 -> 0.822 | Helped |
| DATA-GRU vs InterpNet | IMTS models · MIMIC-III in-hospital mortality | AUC: 0.903 -> 0.919 | Helped |
