Difficulty: Medium
About this MCQ
This Medium Artificial Intelligence & Machine Learning MCQ checks one syllabus fact.
The question is: “An unsupervised learning technique that groups similar data points together based on shared characteristics. What is this concept called?”
The accepted answer is D. Clustering. “An unsupervised learning technique that groups similar data points together based on shared characteristics. What is this concept called” is answered by Clustering (option D). Option A (“Computer vision”) does not match the stem; it is a near-miss used to catch incomplete recall of Clustering. Option B (“Bias-variance tradeoff”) does not match the stem; it is a near-miss used to catch incomplete recall of Clustering. Remaining alternatives (Feature (machine learning)) fall outside the same rule and should be eliminated once Clustering is identified. Artificial Intelligence & Machine Learning questions of this type reward precise definitions rather than approximate associations. Artificial Intelligence & Machine Learning recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
