Machine Learning Tutorial 12 - K-Nearest Neighbours (KNN algorithm)

In this video, we’ll talk about K-Nearest Neighbours. The K-nearest 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 non-parametric learning algorithm, which means that it doesn’t as
