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.

May 22, 2025 · K-nearest neighbor (KNN) is a non-parametric, supervised machine learning algorithm that classifies a new data point based on the classifications of its closest neighbors, and is used for …

Jul 2, 2025 · KNN classifies or predicts outcomes based on the closest data points it can find in its training set. Think of it as asking your neighbors for advice; whoever’s closest gets the biggest say.

6 days ago · KNN Boundaries: The decision boundary for KNN is determined by regions where the classification changes based on the nearest neighbors. K approaches infinity, these boundaries …
