WebSep 10, 2024 · The k-nearest neighbors (KNN) algorithm is a simple, supervised machine learning algorithm that can be used to solve both classification and regression problems. … The K-Nearest Neighbors (K-NN) algorithm is a popular Machine Learning algorithm used mostly for solving classification problems. In this article, you'll learn how the K-NN algorithm works with practical examples. We'll use diagrams, as well sample data to show how you can classify data using the K-NN algorithm. See more The K-NN algorithm compares a new data entry to the values in a given data set (with different classes or categories). Based on its closeness or similarities in a given range (K) of … See more With the aid of diagrams, this section will help you understand the steps listed in the previous section. Consider the diagram below: The graph above represents a data set consisting of two classes — red and blue. A new data entry … See more There is no particular way of choosing the value K, but here are some common conventions to keep in mind: 1. Choosing a very low value will … See more In the last section, we saw an example the K-NN algorithm using diagrams. But we didn't discuss how to know the distance between the new … See more
