ISACA Certified Artificial Intelligence Auditor (CAIA) — Question 15

Which of the following BEST improves predictions and understanding to refine the accuracy of AI models?

Answer options

• A. Data augmentation
• B. Mean clustering
• C. Prompt templates
• D. Data compression

Correct answer: A

Explanation

Data augmentation is the process of adding diverse data samples to improve model training, which leads to better predictions and understanding. Mean clustering, prompt templates, and data compression do not directly enhance the data diversity or quality necessary for refining AI model accuracy.
