    Formula for Recall:
    Recall=True PositivesTrue Positives+False Negatives\text{Recall} = \frac{\text{True Positives}}{\text{True Positives} + \text{False Negatives}}

3. F1-Score

A harmonic mean of Precision and Recall, balancing both metrics.
Formula:
F1-Score=2⋅Precision⋅RecallPrecision+Recall\text{F1-Score} = 2 \cdot \frac{\text{Precision} \cdot \text{Recall}}{\text{Precision} + \text{Recall}}

4. ROC-AUC
