Boosting Learner Loop Start

Together with the corresponding loop end node a boosting loop can be constructed. It repeatedly trains simple models and weights them according to their classification error. The algorithm used is AdaBoost.SAMME, i.e. is can also cope with multi-class problems. The first output contains the re- and over-sampled dataset, rows that have been predicted wrong are contained more often than correctly predicted rows.

Input ports

1. Type: Table
   Input
   Any input data with nominal class labels

Output ports

1. Type: Table
   Training data
   Possibly re-sampled training data, must be connected to the learner node inside the loop
2. Type: Table
   Output
   Unaltered input data, must be connected to the predictor node inside the loop
