Question 32
Domain 2: Describe fundamental principles of machine learning on AzureWhat is an example of clustering?
Correct answer: B
Explanation
Clustering is an unsupervised method that groups similar items based on shared features. "Grouping flowers based on the number of leaves and petals" fits this definition because the flowers are organized by measurable attributes rather than labeled categories.
Why each option is right or wrong
A. Predicting the species of a penguin
B. Grouping flowers based on the number of leaves and petals
Clustering is an unsupervised learning task, so the items are organized by similarity in observed features rather than by a preassigned label. In this example, the flowers are grouped using measurable attributes—the counts of leaves and petals—which is exactly the kind of feature-based partitioning clustering methods produce.
C. Predicting the fuel efficiency of a car
D. Predicting whether a patient is at risk for diabetes
