K-Nearest Neighbors, or KNN, is one of the most intuitive supervised learning methods: to predict a new point, it finds the k training examples that are closest under a chosen distance metric, then uses those neighbors to make the prediction. In classification, the prediction is usually a majority vote of nearby labels; in regression, it […]
