However, the zeta potential of OA-CTS at a weight ratio of 4:5 was significantly lower than that of other groups ( P <0.05), and PDI was higher than that of other groups ( P <0.05). lagu gelang sipaku gelangWebimblearn.metrics.geometric_mean_score. The geometric mean (G-mean) is the root of the product of class-wise sensitivity. This measure tries to maximize the accuracy on each of the classes while keeping these accuracies balanced. For binary classification G-mean is the squared root of the product of the sensitivity and specificity. lagu gembala baik bersuling nan merdu
