Dagging
Package
weka.classifiers.meta
Synopsis
This meta classifier creates a number of disjoint, stratified folds out of the data and feeds each chunk of data to a copy of the supplied base classifier. Predictions are made via majority vote, since all the generated base classifiers are put into the Vote meta classifier.
Useful for base classifiers that are quadratic or worse in time behavior, regarding number of instances in the training data.

Available in Weka 3.6.x - 3.7.1. Available via the package management system for Weka >= 3.7.2 (dagging).
