    K-Nearest Neighbor(KNN) is a machine learning algorithm that is used for both supervised and unsupervised learning. It can be used both for classification and regression problems. The un-labelled data is classified based on the K Nearest neighbors. If the value of K is too high, the noise is suppressed but the class distinction becomes difficult
