Ml classification

Apr 30, 2021 · F-Measure = (2 * Precision * Recall) / (Precision + Recall) The F-Measure is a popular metric for imbalanced classification. The Fbeta-measure measure is an abstraction of the F-measure where the balance of precision and recall in the calculation of the harmonic mean is controlled by a coefficient called beta.
