||
|---|---|---|---|---|
| Type of frequency | Beat | Time | Beat | Time |
| LF/HF | 0.080 | 0.076 | 0.054 | 0.064 |
| PCA | 0.070 | 0.058 | 0.072 | 0.085 |
| MCE | 0.067 | 0.070 | 0.066 | 0.071 |
| WHRV* | 0.080 | 0.067 | 0.050 | 0.054 |
| Random | 0.034 | 0.018 | ||
Bold indicates the higher AUC in each pair (time vs beat).
*Indicates WHRV (the supervised approach) was trained on dataset D1 and the reported results are averaged over patients that the model was not trained on.
