F1 Score
Frequently Asked Questions
What is the formula for F1 Score?▼
`F1 = 2 * (Precision * Recall) / (Precision + Recall)`.
Why not just use accuracy instead of F1 Score?▼
Because accuracy can be misleading on imbalanced datasets. If 99% of emails are not spam, a model that classifies everything as non-spam has 99% accuracy but an F1 score of 0.
