AI0-001 AI Concepts and Foundations Practice Question
A government agency is deploying an AI model to screen loan applications. The model uses features like income, credit score, employment history, and zip code. During fairness auditing, the model is found to deny a disproportionately high number of applicants from a particular demographic group, even when controlling for legitimate financial factors. The agency wants to mitigate this bias without significantly reducing overall accuracy. Which approach should the data scientist prioritize?
⚠ Common exam trap
The AI0-001 exam often tests the misconception that simply removing a sensitive feature (like zip code) or reweighting data is sufficient to eliminate bias, when in reality bias can be encoded through correlated proxies and requires algorithmic debiasing during training.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use adversarial debiasing during model training
Adversarial debiasing is the correct approach because it directly optimizes the model to remove sensitive information (e.g., demographic group membership) from its internal representations while preserving predictive accuracy. This technique trains a primary model to predict the target (loan approval) and an adversary to predict the protected attribute from the model's learned features, forcing the primary model to learn representations that are both accurate and unbiased. It addresses the root cause of bias—correlation between protected attributes and model predictions—without requiring post-hoc threshold adjustments or sacrificing overall performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Adjust the decision threshold for the affected group
Why it's wrong here
Post-hoc threshold adjustments can reduce disparity but often reduce overall model performance and may be seen as unfair.
- ✗
Remove the zip code feature from the model
Why it's wrong here
Zip code is a proxy for race, but other features like income may also be proxies; removal alone is insufficient.
- ✗
Apply sample weighting to balance the demographic groups
Why it's wrong here
Reweighting can reduce bias but may lead to loss of information and hurt overall accuracy.
- ✓
Use adversarial debiasing during model training
Why this is correct
Adversarial debiasing forces the model to learn representations that are invariant to sensitive attributes, reducing bias with minimal accuracy loss.
