WebApr 15, 2024 · The k-nearest neighbour (KNN) algorithm is a supervised machine learning algorithm predominantly used for classification purposes. It has been used widely for … WebJun 26, 2024 · 40. The k-nearest neighbor algorithm relies on majority voting based on class membership of 'k' nearest samples for a given test point. The nearness of samples is typically based on Euclidean distance. Consider a simple two class classification problem, where a Class 1 sample is chosen (black) along with it's 10-nearest neighbors (filled green).
