Question 26
Domain 2 — Data, Machine Learning, and Model DevelopmentWhich of the following trains a predictive model from input data?
Correct answer: C
Explanation
Machine learning is the field that uses input data to learn patterns and build a predictive model. A predictive model is trained from examples so it can make predictions on new data.
Why each option is right or wrong
A. Expert system
B. Artificial intelligence
C. Machine learning
Machine learning is the only option that describes a process of fitting a model to observed input data so it can infer patterns and generate predictions on unseen cases. In standard terminology, a predictive model is trained on examples rather than hand-coded, which distinguishes it from rule-based programming or simple data storage.
