Instance classification assumption
NettetThis article covers how and when to use k-nearest neighbors classification with scikit-learn. Focusing on concepts, workflow, and examples. We also cover distance metrics and how to select the best value for k using cross-validation. This tutorial will cover the concept, workflow, and examples of the k-nearest neighbors (kNN) algorithm.
