Precision, Recall, and F1

Trade-offs you must understand.

Beyond One Number

To see past accuracy you split results into four buckets per class. From them come precision, recall, and F1, the metrics that matter.

The Positive Class

Pick the class you care about as positive, like spam or fraud. Precision and recall both describe how well you handle that class.
