What is K-Nearest Neighbours K-Nearest Neighbours (KNN) is a simple and intuitive supervised machine learning algorithm that makes predictions based on how similar things are to each other. They can be used for classification and regression Imagine you have a scatter plot with red and blue points, where red points represent one class and blue points represent another class. Now, let's say you get a new data point you haven't seen before, and want to know if it should be red or blue KNN looks at
