Table 4.
Precision, recall rates and F1 score of ResNet152 on test set for each CVM subgroup
| Precision | Recall | F1 score | Sample size of each subgroup | |
|---|---|---|---|---|
| CS1 | 0.74 | 0.79 | 0.77 | 154 |
| CS2 | 0.52 | 0.52 | 0.52 | 153 |
| CS3 | 0.59 | 0.56 | 0.58 | 151 |
| CS4 | 0.73 | 0.66 | 0.69 | 151 |
| CS5 | 0.66 | 0.64 | 0.65 | 152 |
| CS6 | 0.77 | 0.84 | 0.81 | 153 |
Precision = TP/TP +FP; Recall = TP/TP +FN; F1 score = 2*Precision * Recall/Precison + Recall. TP is true CVM, cervical vertebral maturation; Precison, Recall and F1 score are calculated as follows with confusion matrix in Figure 3.positive, FP is false positive, FN is false negative, and TN is true negative.
