If f1 score is high
WebThe F-score is a ratio of two variables: F = F1/F2, where F1 is the variability between groups and F2 is the variability within each group. In other words, a high F value (leading to a significant p-value depending on your alpha) means that at least one of your groups is significantly different from the rest, but it doesn't tell you which group.

WebThe F1 score takes into account both the true positive rate and the false positive rate, providing a more complete picture of model performance than relying on accuracy alone. In this way, the F1 score can help identify problems such as unbalanced classes, where a model may achieve high accuracy by simply predicting the majority class. Web11 feb. 2016 · The Dice coefficient (also known as the Sørensen–Dice coefficient and F1 score) is defined as two times the area of the intersection of A and B, divided by the sum of the areas of A and B: Dice = 2 A∩B / ( A + B ) = 2 TP / (2 TP + FP + FN) (TP=True Positives, FP=False Positives, FN=False Negatives) Dice score is a performance metric …
