WebApr 21, 2024 · K Nearest Neighbor algorithm falls under the Supervised Learning category and is used for classification (most commonly) and regression. It is a versatile algorithm also used for imputing missing values and resampling datasets. WebK-nn (k-Nearest Neighbor) is a non-parametric classification and regression technique. The basic idea is that you input a known data set, add an unknown, and the algorithm will tell you to which class that unknown data point belongs. The unknown is classified by a simple neighborly vote, where the class of close neighbors “wins.”
