What is the K-Nearest Neighbor (KNN) Algorithm?

Join Martin Keen as he provides an in-depth explanation of the K-Nearest Neighbors (KNN) algorithm, a popular classification and regression classifier in machine learning. Martin covers the basics of KNN, including its assumption that similar data points are located near each other, and how it works with examples - as well as the strengths and weaknesses of KNN, including its simplicity, adaptability, and scalability issues.
