AWS Certified AI Practitioner (AIF-C01) — Question 132

A company wants to find groups for its customers based on the customers’ demographics and buying patterns.

Which algorithm should the company use to meet this requirement?

Answer options

• A. K-nearest neighbors (k-NN)
• B. K-means
• C. Decision tree
• D. Support vector machine

Correct answer: B

Explanation

The K-means algorithm is ideal for clustering based on demographics and buying patterns, as it groups data points into clusters based on similarity. K-nearest neighbors (k-NN) is used for classification rather than clustering, while decision trees and support vector machines are more suited for predictive modeling rather than grouping similar data.
