Definition: You are given a question on machine learning. You are also given 4 answer options (associated with "A", "B", "C", "D"), out of which only one is correct. You need to answer the question by selecting the correct option. You should only answer with the choice letter, not the whole answer.
Input: Traditionally, when we have a real-valued input attribute during decision-tree learning we consider a binary split according to whether the attribute is above or below some threshold. Pat suggests that instead we should just have a multiway split with one branch for each of the distinct values of the attribute. From the list below choose the single biggest problem with Pat’s suggestion:
(A)It is too computationally expensive. (B)It would probably result in a decision tree that scores badly on the training set and a testset. (C)It would probably result in a decision tree that scores well on the training set but badly on a testset. (D)It would probably result in a decision tree that scores well on a testset but badly on a training set.
