(I) Monte Carlo cross-validation performed in k rounds. In each round, the training and testing samples are randomly selected without replacement from the original data. (II) The bootstrapping process can be performed in B rounds. In each round, the training data are generated by randomly sampling from the original data with replacement. The samples that are not included in the training dataset (i.e., out-of-bag samples) form the testing dataset.
