CompTIA DataX (DY0-001) — Question 29

A data scientist built several models that perform about the same but vary in the number of features. Which of the following models should the data scientist recommend for production according to Occam's razor?

Answer options

• A. The model with the fewest features and highest performance
• B. The model with the fewest features and the lowest performance
• C. The model with the most features and the lowest performance
• D. The model with the most features and the highest performance

Correct answer: A

Explanation

According to Occam's razor, the simplest solution is often the best. Therefore, the model with the fewest features and the highest performance (Option A) is preferred because it is less complex and easier to maintain. The other options involve either lower performance or unnecessary complexity, which goes against the principle of Occam's razor.
