(2) State whether the following statements are true or false. Justify your answer. (a) Suppose S is a training dataset where each feature vector Xi is unique. Then the ID3 Decision tree constructed on S (without pruning) has zero training error. (b) Pruning an ID3 Decision Tree will never increase its validation error.
