K-Nearest Neighbours (KNN): MCQ Practice
KNN is one of the simplest ML algorithms, yet it requires careful thinking about distance metrics, feature scaling and the choice of K. These questions help you build that intuition.
Learning by Example
KNN classifies new points based on the majority class among their closest neighbours in feature space.
KNN Workflow
Scale Features → Choose K & Distance Metric → Store Training Data → Predict via Nearest Neighbours
