What is k-Nearest Neighbors (k-NN)?
k-Nearest Neighbors is a simple algorithm that stores all available cases and classifies new cases based on a similarity measure (e.g., distance functions). KNN is a "lazy instance based" algorithm, meaning it does not generalize. Therefore, training a KNN algorithm is insanely fast! For the basic kNN, training happens at literally the speed of just reading all the training data and saving it in a data structure.
If you’d like to benchmark the predictive performance of k-NN against other algorithms contact us for a personalized demo of the Domino Data Science platform.
