AWS Certified AI Practitioner (AIF-C01) — Question 275

A healthcare company is building an AI solution to predict patient readmission within 30 days of patient discharge. The company has trained a model on historical patient data including medical history, demographics, and treatment specifications, to provide readmission predictions in real time.

Which task describes AI model inference in this scenario?

Answer options

• A. Gather historical patient readmission data.
• B. Use appropriate metrics and assess model performance.
• C. Use data to identify patient patterns and correlations.
• D. Use a trained model to predict patient readmission.

Correct answer: D

Explanation

AI model inference refers to the phase where a fully trained model is used to make predictions on new, unseen data, which corresponds to predicting patient readmission in this scenario. Option A describes the data collection phase, Option C relates to data analysis or feature engineering, and Option B describes the model evaluation phase, none of which represent the active inference stage.
