【机器学习】KNN算法介绍及py实现（详细代码，通俗易懂）_python实现knn分类器的设计CSDN博客
Video. The K-Nearest Neighbors (KNN) algorithm is a supervised machine learning method employed to tackle classification and regression problems. Evelyn Fix and Joseph Hodges developed this algorithm in 1951, which was subsequently expanded by Thomas Cover. The article explores the fundamentals, workings, and implementation of the KNN algorithm.
Yuk Kenali Apa itu Algoritma KNearest Neighbors (KNN) Trivusi
The algorithm is quite intuitive and uses distance measures to find k closest neighbours to a new, unlabelled data point to make a prediction. Because of this, the name refers to finding the k nearest neighbors to make a prediction for unknown data. In classification problems, the KNN algorithm will attempt to infer a new data point's class.

Implementasi Data Mining Menggunakan Algoritma k Nearest Neighbor KNN
KNN is a lazy learning algorithm. KNN classifies the data points based on the different kind of similarity measures (e.g. Euclidean distance etc). In KNN algorithm 'K' refers to the number of neighbors to consider for classification. It should be odd value. The value of 'K' in KNN algorithm must be selected carefully otherwise it may.
