Question

When using out-of-bag evaluation, each predictor in a bagging ensemble is evaluated using instances that it was not trained on (because they did came out in the random sampling). This facilitates a mostly unbiased evaluation of the ensemble without recurring to a separate validation set. Therefore, there are more instances left available for training and the ensemble can perform a little better. O True O False
