WebMar 29, 2024 · KNN which stand for K Nearest Neighbor is a Supervised Machine Learning algorithm that classifies a new data point into the target class, depending on the features of its neighboring data points. Let’s try to understand the KNN algorithm with a simple example. Let’s say we want a machine to distinguish between images of cats & dogs. WebThe simplest way to perform KNN in R is with the package class. It has a KNN function that is rather user friendly and does not require you to do distance computing as it runs everything with Euclidean distance. For more advanced types of nearest neighbors matching it would be best to use the matchit function from the matchit package.
