Because of this you will need to define the probability boundary between classes before using F1, unlike with AUC, and you will find that your F1 score changes depending on where it is set. F1 score vs AUC on imbalanced datasets. WebFeb 4, 2013 · 6. The F-measure is the harmonic mean of your precision and recall. In most situations, you have a trade-off between precision and recall. If you optimize your classifier to increase one and disfavor the other, the harmonic mean quickly decreases. It is greatest however, when both precision and recall are equal.
