Which of the following statements is true about multi – stage combination methods? Correct Answer The next base – learner is trained on only the instances where the previous base – learners are not accurate enough

It is a serial approach; the next base – learner is trained or tested on only the instances where the previous base – learners are not accurate enough. A multi – stage combination method is neither a parallel approach nor a selection approach. The base – learners are sorted in increasing complexity.
