F1 score (Geron Eq 3-3, morie.fn grf1)

Counts delegated to morie_geron_confusion_matrix().

Usage

morie_geron_f1_score(y_true, y_pred, positive_class = 1)

Arguments

y_true, y_pred

Non-negative integer labels.

positive_class

0-based class to score.

Value

List with f1, precision, recall, macro_f1, per_class_f1, confusion_matrix.
