Question 6

+5 marksOne or more correct options

Consider the following adaboost models:

Which of the following statements are MOST accurate?

Consider the following adaboost models:

Select all that apply.

  1. A

    adb1 is less likely to overfit than adb2 because its base trees are shallower.

  2. B

    Increasing n_estimators always improves test accuracy for AdaBoost.

  3. C

    Learning rate affects the contribution of each base learner; a smaller learning rate always reduces training accuracy.

  4. D

    adb2 with deeper trees will have lower bias but higher variance than adb1.
