StackedDatasetClassifierTeacher

public StackedDatasetClassifierTeacher(Dataset dataset,
                                       boolean activeLearning)

Parameters:

activeLearning - if true, all learning is active - ie nothing is pushed at the learner, everything must be 'pulled' via queries. if false, all examples fron the dataset are 'pushed' at the learner via addExample.
