KNNImputer for Filling Missing Data in Data Preprocessing
K-Nearest Neighbors (KNN) Algorithm for Handling Missing Data
The K-Nearest Neighbors (hereafter, KNN) is a supervised machine-learning algorithm that uses a k number of nearest (closest) neighbors to classify an instance into a relevant class.
Neighbors of an instance are found using the Euclidean distance. The Euclidean distance between two data points is calculated using the foll…
