dagging.DaggingRegressor

class dagging.DaggingRegressor(base_estimator=None, n_estimators=10, random_state=None)

A Dagging regressor. This meta regressor creates a number of disjoint, stratified folds out of the data and feeds each chunk of data to a copy of the supplied base regressor. Predictions are made via hard or soft voting. Useful for base regressor that are quadratic or worse in time behavior, regarding number of instances in the training data.

Parameters

base_estimatorobject or None, optional (default=None)

The base estimator to fit on random subsets of the dataset. If None, then the base estimator is a decision tree.

n_estimatorsint, optional (default=3)

The number of base estimators in the ensemble.

random_stateint, RandomState instance or None, optional (default=None)

If int, random_state is the seed used by the random number generator; If RandomState instance, random_state is the random number generator; If None, the random number generator is the RandomState instance used by np.random.

Attributes

base_estimator_estimator

The base estimator from which the ensemble is grown.

estimators_list of estimators

The collection of fitted base estimators.
