F1

Caesar AI Atlas Definition

F1 — это классификационная метрика, которая объединяет precision и recall в один показатель с помощью их гармонического среднего. Она полезна, когда важны и false positives, и false negatives, и обычно штрафует сильные дисбалансы между precision и recall.

Other Definitions

A "roll-up" binary classification metric that relies on both precision and recall. Here is the formula: Suppose precision and recall have the following values: - precision = 0.6 - recall = 0.4 You calculate F~1~ as follows: When precision and recall are fairly similar (as in the preceding example), F~1~ is close to their mean. When precision and recall differ significantly, F~1~ is closer to the lower value. For example: - precision = 0.9 - recall = 0.1
