WebThe K-nearest neighbor (KNN) classifier is one of the simplest and most common classifiers, yet its performance competes with the most complex classifiers in the literature. The core of this classifier depends mainly on measuring the distance or similarity between the tested examples and the training examples.

WebThe K-NN working can be explained on the basis of the below algorithm: Step-1: Select the number K of the neighbors. Step-2: Calculate the Euclidean distance of K number of neighbors. Step-3: Take the K nearest neighbors as per the calculated Euclidean distance. Step-4: Among these k neighbors, count the number of the data points in each category.
