ISACA Certified Artificial Intelligence Auditor (CAIA) — Question 33

During an audit of an AI solution, the modeler informs the IS auditor that data augmentation techniques were utilized. Which of the following BEST enables the auditor to determine the effectiveness of the data augmentation?

Answer options

• A. Balance of data classes prior to and after augmentation
• B. Performance metrics of the model prior to and after augmentation
• C. Affinity and diversity of augmented data compared to original data
• D. Feature importance summary of the model prior to and after augmentation

Correct answer: B

Explanation

The correct answer is B because performance metrics provide a direct measure of how the model's accuracy and effectiveness have changed due to data augmentation. Options A, C, and D do not directly measure the impact on model performance, making them less effective for the auditor's assessment.
