Question 20

+3 marksOne correct option

Consider the following assertion and reason. Select the correct option.
Assertion (A): Increasing the number of estimators in AdaBoost can sometimes reduce the test accuracy, even though the training error continues to decrease.
Reason (R): In AdaBoost, after each iteration, the weights of correctly classified training samples are increased so that future weak learners focus more on these correct samples. Choose the correct option:

  1. A

    Both A and R are true, and R is the correct explanation of A.

  2. B

    Both A and R are true, but R is not the correct explanation of A.

  3. C

    A is true, but R is false.

  4. D

    A is false, but R is true.

Show answer
