WebMar 20, 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 algorithm is based on the principle that similar data points (i.e. data points that are nearby in space) tend to have similar labels (i.e. they tend to belong to the same class). WebApr 10, 2024 · K-Nearest Neighbors (KNN) is a non-parametric supervised learning technique applied to classification and regression problems. KNN is one of the simplest machine learning algorithms. It consists of classifying the input into the category that is most similar among the available categories. The decision regarding the chosen class is based on the ...
