AWS Certified AI Practitioner (AIF-C01) — Question 265

Which ML technique uses training data that is labeled with the correct output values?

Answer options

• A. Supervised learning
• B. Unsupervised learning
• C. Reinforcement learning
• D. Transfer learning

Correct answer: A

Explanation

Supervised learning is the correct answer because it specifically utilizes labeled training data to map inputs to known correct outputs. Unsupervised learning deals with unlabeled data to identify underlying patterns, reinforcement learning uses trial-and-error with a reward system, and transfer learning applies a pre-trained model's knowledge to a new, related task.
