AWS Certified AI Practitioner (AIF-C01) — Question 334

What does inference refer to in the context of AI?

Answer options

• A. The process of creating new AI algorithms
• B. The use of a trained model to make predictions or decisions on unseen data
• C. The process of combining multiple AI models into one model
• D. The method of collecting training data for AI systems

Correct answer: B

Explanation

In artificial intelligence, inference is the operational phase where a previously trained machine learning model is applied to new, unseen data to output predictions or classifications. This is distinct from the training phase, which involves feeding data to the model so it can learn, and from algorithm creation or data collection. Therefore, using a trained model to draw conclusions from new inputs is the correct definition.
