kNN, or the k-nearest neighbor algorithm, is a machine learning algorithm that uses proximity to compare one data point with a set of data it was trained on and has memorized to make predictions.

KNN is a simple, supervised machine learning (ML) algorithm that can be used for classification or regression tasks - and is also frequently used in missing value imputation.

The KNN algorithm is one of the simplest machine learning algorithms: It assigns to the profile or feature vector xi the most common modality of Y among its k “nearest neighbors.”
