f1 score

How is the F1 Score Calculated?

The F1 score is calculated using the formula:
\[ F1 \, Score = 2 \times \left( \frac{Precision \times Recall}{Precision + Recall} \right) \]
Here, precision and recall are derived from the confusion matrix, which includes true positives (TP), false positives (FP), true negatives (TN), and false negatives (FN).
\[ Precision = \frac{TP}{TP + FP} \]
\[ Recall = \frac{TP}{TP + FN} \]
