Problem

Difference between knn and kmeans

Asked in the Technical video round (40 min) stage. This was the first of three questions in the single technical round; the account files it under “ML Question.” Explain the distinction clearly, including whether each method is supervised or unsupervised, how training and inference work, the role of k, computational complexity, assumptions, and suitable use cases. Include important limitations and explain how you would evaluate each method in practice.
