k-nnK - NN algorithm (K on his Neighbor, K Nearest Neighbor algorithm), is a classical algorithm of machine learning, more simple and easy to understand. K - NN algorithm by calculating the new data and the distance between the training data characteristic value, and then select K (K > = 1) from the Nearest Neighbor classification or regression. If K = 1, then the new data will be class assigned to its neighbours.
