Brain age prediction model comparison based on MAE and correlation between true and predicted agea
| Model | MAE Raw | MAE Corr. | Correlation Raw | Correlation Corr. |
|---|---|---|---|---|
| RFC | 3.16 | 2.89 | 0.70 (P < .001) | 0.84 (P < .001) |
| SVM (reg.) | 3.54 | 2.66 | 0.66 (P < .001) | 0.86 (P < .001) |
| Log. Reg. | 4.06 | 3.10 | 0.56 (P < .001) | 0.79 (P < .001) |
| RFR | 3.21 | 2.46 | 0.74 (P< .001) | 0.87 (P < .001) |
Note:—corr. indicates corrected; reg., regression; Log. Reg, Logistic Regression.
↵a Results using the raw and corr. brain ages are shown for comparison.
