data mining algorithm ensemble algorithm Ensemble algorithms are algorithms that generate an ensemble when executed on a dataset. The ensemble algorithms include a specification of single generalization algorithms which are executed in oreder to produce the single generalizations that compose the ensemble. Examples of ensemble algorithms include bagging, boosting, stacking, random forests, random subspaces,bagging of random subspaces etc. For example, bagging of decision trees algorithm includes the specification of a bagging algorithm and having a decision tree algorithm for generating the base models composing the ensemble. single generalization algorithm
