One way to get a diverse set of classifiers is to use the same training algorithm for every predictor, but train them on different random subsets of the training set. Two forms of this are known as bagging and pasting. Bagging is done when sampling with the above method is performed _____________, while Pasting is done when sampling with the above method is performed _____________.
