GenAI Basics · Question 7 · Medium
What is the cosine similarity between the vectors (3, 4) and (6, 8)?
- 0.5
- 1
- 0
- 10
Answer and explanation
Answer: B. 1
Explanation: Cosine similarity = (a·b) / (|a||b|) = (18 + 32) / (5 × 10) = 50 / 50 = 1. The vectors point in the same direction, so the similarity is the maximum value even though their lengths differ.
