Model F1 Score
Score
The F1 Score is the harmonic mean of Precision and Recall, providing a balance between them. It’s used when an equilibrium between Precision and Recall is desired.
Formula
2 * ((Precision * Recall) / (Precision + Recall))
Example
If the precision is 80% and recall is 60%, the F1 score is 2*((0.8*0.6)/(0.8+0.6)) = 0.69.
