A grid holds three values for one setting and two values for another and the cross validation uses two folds. How many fits does the search perform before the final one?

選択肢

1. The count is the sum of the size of the grid and the count of folds so the search fits eight different models.
2. The count is the number of folds alone so the search fits two models and averages their settings.
3. The count is the size of the grid alone so the search fits six models and reuses a single split for all of them.
4. The count is the product of the size of the grid and the number of folds so the search fits twelve different models.
