The k-nearest neighbor algorithm, commonly known as the KNN algorithm, is a simple yet effective classification and regression supervised machine learning algorithm. This article will be covering the KNN Algorithm, its applications, pros and cons, the math behind it, and its implementation in Python. Please make sure to check the entire…
