Machine Learning Tutorial 12 K Nearest Neighbours ( KNN algorithm)

In this video, we ll talk about KNearest Neighbours. The Knearest neighbors (KNN) algorithm is a type of supervised machine learning algorithms. KNN is extremely easy to implement in its most basic form, and yet performs quite complex classification tasks. It is a lazy learning algorithm since it doesn t have a specialized training phase. Rather, it uses all of the data for training while classifying a new data point or instance. KNN is a nonparametric learning algorithm, which means that it doesn t as
