What is the F1-Score, and why might you use it instead of Precision and Recall?

  • Arithmetic mean of Precision and Recall
  • Geometric mean of Precision and Recall
  • Harmonic mean of Precision and Recall
  • nan
The F1-Score is the harmonic mean of Precision and Recall. It balances both metrics and is particularly useful when you need to seek a balance between Precision and Recall and there is an uneven class distribution.
