AI0-001 AI Security, Ethics and Governance Practice Question
A financial institution uses an AI model to approve loan applications. The model was trained on historical data that included biased lending practices. The bank's ethics committee wants to mitigate bias without removing protected attributes. Which approach best balances fairness and model performance?
⚠ Common exam trap
CompTIA often tests the misconception that simply removing protected attributes (Option B) is sufficient to eliminate bias, when in reality proxy features and correlated variables can perpetuate discrimination.

Correct answer & explanation
✓
Apply adversarial debiasing during training
Adversarial debiasing is the best approach because it directly optimizes the model to reduce bias during training while preserving predictive accuracy. It uses an adversarial network that tries to predict the protected attribute from the model's predictions, forcing the main model to learn representations that are less correlated with that attribute. This allows the bank to keep protected attributes in the data (as required by the ethics committee) while actively mitigating bias.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Retrain the model using a balanced dataset
Why it's wrong here
Balancing data improves representation but does not eliminate bias from feature interactions.
- ✗
Remove all protected attributes from the training data
Why it's wrong here
Bias can persist through correlated features, so removal alone is insufficient.
- ✗
Post-process model outputs to adjust for demographic parity
Why it's wrong here
Post-processing can hurt performance and may not address root cause.
- ✓
Apply adversarial debiasing during training
Why this is correct
Adversarial debiasing reduces bias by learning non-discriminatory representations.
