Lesson Overview

2.18 – k-Nearest Neighbors (k-NN) Algorithm: The k-Nearest Neighbors algorithm predicts outcomes based on the closest data points in the training set. It’s intuitive, relying on similarity rather than explicit learning. The model excels in pattern recognition, anomaly detection, and recommendation systems. Choosing the right number of neighbors (k) is crucial for performance. While computationally heavy for large datasets, k-NN’s simplicity makes it an excellent teaching model. It reflects the idea that similar things behave alike—a fundamental concept in intelligent systems.
