K-Nearest Neighbors Classification Explained
This animation shows how the K-nearest neighbors algorithm classifies a new data point using labeled training data. It visualizes distance calculations from the unknown point to its neighbors, highlights the K=3 closest points, and demonstrates majority voting to determine the predicted class. Clean diagrams, arrows, and captions make the geometric intuition behind KNN clear. Useful for students and teachers introducing supervised learning and instance-based classification methods in machine learning courses.

The prompt that made it
Create a 90-second 2D animated educational video explaining KNN classification. Show labeled training data, introduce a new unknown point, animate distance measurement, identify K=3 nearest neighbours, demonstrate majority voting, and show the final class prediction. Use clean academic diagrams, moving data points, labels, arrows and highlights. Include professional English narration and captions. No human avatar. 16:9 landscape.
Make the next one in this series
- Show how changing the value of K affects KNN decision boundaries.
- Explain how Euclidean versus Manhattan distance changes KNN results.
- Demonstrate KNN regression using averaging instead of majority voting.
