WebDec 19, 2008 · Bootstrap aggregation, or bagging, is a method of reducing the prediction error of a statistical learner. The goal of bagging is to construct a new learner which is the expectation of the original learner with respect to the empirical distribution function. WebInstead of predicting with the best hypothesis in the hypothesis class, that is, the hypothesis that minimizes the training error, our algorithm predicts with a weighted average of all …

WebThe bounds we derived based on VC dimension were distribution independent. In some sense, distribution independence is a nice property because it guarantees the bounds to hold for any data distribution. On the other hand, the bounds may not be tight for some speci c distributions that are more benign than the worst case.
