CompTIA DataX (DY0-001) — Question 31

The most likely concern with a one-feature, machine-learning model is high error due to:

Answer options

• A. bias.
• B. dimensionality.
• C. variance.
• D. probability.

Correct answer: A

Explanation

The correct answer is A, as a one-feature model often oversimplifies the problem, leading to systematic errors, known as bias. Options B, C, and D do not directly relate to the shortcomings of a model that relies on a single feature, as they pertain to different aspects of model complexity and data representation.
