    How about bagging with models other than decision trees? How can we do bagging in r with, for example, SVM or ANN?

    Thnak you Sir for your videos....I noticed a small mistake in the AUC curve you show in the beginning of this video...in the x axis we take (1-specificity).

    • @bkrai
      @bkrai  3 года назад +1

      X axis values are in reverse order. That's same as 1-specificity.

      They are 2 different methods and may give better with type of data you are using.
