Table 4. Binary classification accuracy comparing each algorithm for predicting “high” risk of mortality in the test cohort (n = 125,657).
Algorithm | Optimal Threshold | Correctly Classified Death | Correctly Classified Alive | Sensitivity | Specificity |
---|---|---|---|---|---|
Deep Learning | > 2% | 2,343/3,608 | 92,978/122,049 | 64.9% | 76.2% |
Random Forest | > 5% | 2,300/3,608 | 94,603/122,049 | 63.7% | 77.5% |
Adjusted Cox Model | > 6% | 2,197/3,608 | 92,832/122,049 | 60.9% | 76.1% |
Age/Gender Cox Model | > 8.4% | 1,728/3,608 | 93,661/122,049 | 43.7% | 76.7% |
