One of the easiest supervised machine learning methods for classification is K-Nearest Neighbors. A data point is classified depending on the types of its neighbors. It archives all cases in its database and groups fresh cases according to characteristics in typical. .https://1stepgrow.com/course/advance-data-science-and-artificial-intelligence-course/
