AdditiveRegression (3.7)

Learner

Meta classifier that enhances the performance of a regression base classifier

Each iteration fits a model to the residuals left by the classifier on the previous iteration.Prediction is accomplished by adding the predictions of each classifier.

Reducing the shrinkage (learning rate) parameter helps prevent overfitting and has a smoothing effect but increases the learning time.

(based on WEKA 3.7)
