Show Answer
Correct Answer: B. Unseen data
Explanation:
Overfitting harms generalisation.
A. Precision is TP/(TP+FP).
B. Recall is TP/(TP+FN).
C. Accuracy is always suitable for highly imbalanced data.
D. Specificity is TN/(TN+FP).
Show Answer
Correct Answer: A|B|D
Explanation:
Accuracy can be misleading under severe imbalance.
A. The learning rate controls step size.
B. A very large learning rate can cause divergence.
