A) with K-Fold $\bullet$

Multiple Choice

Which of the following statements is false?

A) With K-fold cross-validation, you use all of your data at once for training your model.
B) K-fold cross-validation splits the dataset into k equal-size folds.
C) You then repeatedly train your model with k - 1 folds and test the model with the remaining fold.
D) Consider using k = 10 with folds numbered 1 through 10. With 10 folds, we'd do 10 successive training and testing cycles: $\bullet$ First, we'd train with folds 1-9, then test with fold 10.
$\bullet$ Next, we'd train with folds 1-8 and 10, then test with fold 9.
$\bullet$ Next, we'd train with folds 1-7 and 9-10, then test with fold 8.
This training and testing cycle continues until each fold has been used to test the model.
