AbstainingCascade |
The specified classifiers represent a cascade: if the first one abstains, the second is used (and so on), otherwise the prediction is returned.
If all classifiers prior to the last one abstained then the prediction of the last one is returned.

class |
ConsensusOrVote |
If the required minimum number of classifiers of the ensemble agree on a label, then this label is predicted.
|
class |
SuppressModelOutput |
Meta-classifier that enables the user to suppress the model output.
Useful for ensembles, since their output can be extremely long.
|
class |
ThresholdedBinaryClassification |
Meta classifier for binary classification problems that allows to specify a minimum probability threshold for one of the labels.
|
class |
Veto |
If the specified label is predicted by the required minimum number of classifiers of the ensemble, then this label is predicted.

VotedImbalance |
Generates an ensemble using the following approach:
- do x times:
* create new dataset, resampled with specified bias
* build base classifier with it
If no classifier gets built at all, use ZeroR as backup model, built on the full dataset.
At prediction time, the Vote meta-classifier (using the pre-built classifiers) is used to determining the class probabilities or regression value.
Instead of just using a fixed number of resampled models, you can also specify thresholds (= probability that the minority class does not meet) with associated number of resampled models to use.
