Question $6$

What is the default behavior for splitting the training set and test set?

Dataiku will perform a random split and allocate $80\%$ of the data to the training set and $20\%$ to the test set.

Dataiku will order the value using a time column and allocate the first half rows to training set and last half rows to test set.

Dataiku will train on the whole sample available to maximize the training set available and test it on the sime sample.

Dataiku will perform a $5-$fold cross validation.
