AI-ENGINEER sample questions

2 questions from the AI-ENGINEER practice set, with the answer and explanation.

  1. Question 1
    A bank wants a model that predicts whether a loan applicant will default, using past applications already labeled as repaid or defaulted. Which learning approach fits this problem?
    • A.
      Supervised classification
    • B.
      Unsupervised clustering
    • C.
      Reinforcement learning
    • D.
      Dimensionality reduction of features
    Show answer

    Correct answer:

    • A.
      Supervised classification

    Explanation

    Supervised classification learns from labeled examples, so it can predict a known outcome such as default for a new applicant. Unsupervised clustering is the tempting choice because it also groups applicants, but it ignores the labels and cannot predict default directly. Reinforcement learning optimizes actions against a reward signal, which does not match a historical labeled dataset.
  2. Question 2
    Accuracy can be misleading when one class is very rare in the dataset.
    • A.
      True
    • B.
      False
    Show answer

    Correct answer:

    • A.
      True

    Explanation

    This is true. A model that predicts the majority class every time can score high accuracy while catching none of the rare cases, which is why precision, recall or PR curves are often more informative for imbalanced data.
