WebOct 22, 2024 · Bootstrap Aggregation, or bagging for short, is an ensemble machine learning algorithm. The techniques involve creating a bootstrap sample of the training dataset for each ensemble member and training a decision tree model on each sample, then combining the predictions directly using a statistic like the average of the predictions. WebJan 2, 2024 · The popular bagging algorithm, random forest, also sub-samples a fraction of the features when fitting a decision tree to each bootstrap sample, thus further …
WebThe second difference from bagging is that the base learning algorithm, e.g. the decision tree, must pay attention to the weightings of the training dataset. ... as there are techniques that may span all groups or implementations that can be configured to realize an example from each group and even bagging-based methods.
