AWS Certified AI Practitioner (AIF-C01) — Question 206

An AI practitioner is evaluating the performance of an Amazon SageMaker model. The AI practitioner must choose a performance metric. The metric must show the ratio of the number of correctly classified items to the total number of correctly and incorrectly classified items.

Which metric meets these requirements?

Answer options

• A. Accuracy
• B. Precision
• C. F1 score
• D. Recall

Correct answer: A

Explanation

The correct answer is Accuracy because it directly measures the ratio of correctly classified items to the total classified items. Precision, F1 score, and Recall focus on different aspects of classification performance and do not represent the overall accuracy of the model.
