                          Classifier[] weakClassifiers,

    • Method Detail

      • getNumWeakClassifiers

        public int getNumWeakClassifiers()
        Get the number of weak classifiers in this ensemble classifier
      • getTrimmedClassifier

        public AdaBoostM2 getTrimmedClassifier​(int numWeakClassifiersToUse)
        Return an AdaBoostM2 classifier that uses only the first numWeakClassifiersToUse weak learners.

        The returned classifier's Pipe and weak classifiers are backed by the respective objects of this classifier, so changes to the returned classifier's Pipe and weak classifiers are reflected in this classifier, and vice versa.

                                       int numWeakClassifiersToUse)
        Classify the given instance using only the first numWeakClassifiersToUse classifiers trained during boosting
