K-nearest neighbours
K-nearest neighbours: A method predicting from the k nearest training examples under a distance metric, without a traditional parametric fitting phase. Scaling, dimensionality and k influence results. Memorisation simplifies training but can make prediction and indexing expensive. This perspective connects the definition with practical behaviour in artificial intelligence systems.
