### H2O Binomial Scorer

Other

Scores binomial classification predictions. Note that the scoring results may differ from the results of the KNIME *Scorer* node. Explanation: H2O optimizes the F1 score *F1=2∗(Precision∗Recall)/(Precision+Recall)* to find the probability threshold, which in turn is used to determine the class of a sample (positive vs. negative).
