WebMay 17, 2024 · K-nearest Neighbor (KNN) is a supervised classification algorithm that is based on predicting data by finding the similarities to the underlying data. KNN is most widely used for classification... WebAug 31, 2024 · KNN is a machine learning technique usually classified as an "Instance-Based predictor". It takes all instances of classified samples and draws them in a n-dimensional space. Using algorithms such as Euclidean distance, KNN looks for the closest points in this n-dimensional space and estimates to which class it belongs based on these neighbors.
