Witrynasklearn.metrics. .precision_score. ¶. Compute the precision. The precision is the ratio tp / (tp + fp) where tp is the number of true positives and fp the number of false positives. The precision is intuitively the ability of the classifier not to label as positive a sample that is negative. The best value is 1 and the worst value is 0.

WitrynaThe relative contribution of precision and recall to the F1 score are equal. The formula for the F1 score is: F1 = 2 * (precision * recall) / (precision + recall) In the multi-class and multi-label case, this is the average of the F1 score of each class with weighting depending on the average parameter.
