IAPP Artificial Intelligence Governance Professional (AIGP) — Question 15

Decreasing the complexity of a machine learning model reduces variance and:

Answer options

• A. Increases bias.
• B. Increases accuracy.
• C. Decreases tolerance.
• D. Decreases interpretability.

Correct answer: A

Explanation

When you decrease the complexity of a model, it tends to generalize better, which results in higher bias as it may oversimplify the data. While this can help reduce overfitting (variance), it does not necessarily improve accuracy or affect tolerance and interpretability in the same way, making option A the correct choice.
