Explain how the F1-Score is computed and why it is used.
- Arithmetic mean of Precision and Recall, balances both metrics
- Geometric mean of Precision and Recall, emphasizes Recall
- Harmonic mean of Precision and Recall, balances both metrics
- nan
F1-Score is the harmonic mean of Precision and Recall. It helps balance both metrics, particularly when there's an uneven class distribution. It's often used when both false positives and false negatives are important to minimize.
