A00-408 sample questions

2 questions from the A00-408 practice set, with the answer and explanation.

  1. Question 1
    Why should a text data set be split into training and validation partitions before the vocabulary is chosen?
    • A.
      Vocabulary choices made on all of the data can leak validation information into the model
    • B.
      Vocabulary must be chosen before any data is read from the source, so validation rows never influence it
    • C.
      Validation partitions cannot contain any stop words at all
    • D.
      Training partitions must contain only lowercase tokens
    Show answer

    Correct answer:

    • A.
      Vocabulary choices made on all of the data can leak validation information into the model

    Explanation

    If the vocabulary is built from every row, terms that only occur in validation rows influence training, which inflates validation scores. Choosing vocabulary before reading any data is the tempting distractor, but the data must be read to build it. The other two statements are not requirements of partitioning.
  2. Question 2
    A confusion matrix for a binary text classifier must have all four cells nonzero to be valid.
    • A.
      True
    • B.
      False
    Show answer

    Correct answer:

    • B.
      False

    Explanation

    A cell can legitimately be zero, for example when the model never predicts the positive class. The tempting error is treating an empty cell as a sign of a broken calculation. Zero counts are informative about where the errors are.
