Description ClassificationKNN is a nearest-neighbor classification model in which you can alter both the distance metric and the number of nearest neighbors. Because a ClassificationKNN classifier stores training data, you can use the model to compute resubstitution predictions. This is a matlab built in function called knnclassify, which is primarily used to identify the nearest neighbour of a data in matrix. The knnclassify () function uses the k-nearest neighbours classification algorithm to perform classification.
