How to interpret f1 scores
Web12 nov. 2024 · If beta is 0 then f-score considers only precision, while when it is infinity then it considers only the recall. When beta is 1, that is F1 score, equal weights are given to both precision and recall. In fact, F1 score is the harmonic mean of precision and recall. F1 = 2 * (precision * recall) / (precision + recall) Web19 mei 2024 · An alternative metric that is often used is called the F1 Score, which takes into account how the data is distributed. For example, if the data is highly imbalanced (e.g. 90% of all players do not get drafted and 10% do get drafted) then F1 score will provide a better assessment of model performance.
