AWS Certified AI Practitioner (AIF-C01) — Question 254

A research company is growing microbiological cultures. The company captures images of the cultures without any prior labeled data about growth areas. The company needs to identify the regions of the images that show culture growth.

Which ML technique will meet these requirements?

Answer options

• A. Logistic regression
• B. Decision tree
• C. Clustering
• D. Dimensionality reduction

Correct answer: C

Explanation

Clustering is the appropriate machine learning technique for this scenario as it can group the data into distinct clusters without prior labels, effectively identifying the growth areas in the images. In contrast, logistic regression and decision trees require labeled data for training, and dimensionality reduction focuses on reducing feature space rather than detecting specific growth regions.
