Performance & Evaluation

F1 Score

A combined measure of precision and recall, the harmonic mean of both.

Definition

The F1 score combines precision and recall into a single metric, giving equal weight to both. It's particularly useful when you want to balance the two, avoiding both false alarms (low precision) and missed cases (low recall). An F1 score of 1.0 is perfect; 0.0 is completely wrong. It's a standard metric for classification tasks where neither precision nor recall alone tells the full story.
