Notation/evaluation index | Description/definition |
---|---|
TP | True positive. The number of patients who had unplanned readmission and were also predicted to have unplanned readmission by the model |
FP | False positive. The number of patients who did not have unplanned readmission but were predicted to have unplanned readmission by the model |
TN | True negative. The number of patients who did not have unplanned readmission and were also not predicted to have unplanned readmission by the model |
FN | False negative. The number of patients who had unplanned readmission but were not predicted to have unplanned readmission by the model |
Precision | TP/(TP + FP) |
Recall | TP/(TP + FN) |
F1-score | The harmonic mean of precision and recall. The formula is as follows: F1 = 2 / (1 / Precision + 1 / Recall) |
AUROC | Area under the receiver operating characteristic curve |
AUPRC | Area under the precision–recall curve |
