WebJun 26, 2024 · 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). WebA k-nearest neighbor (kNN) search finds the k nearest vectors to a query vector, as measured by a similarity metric. Common use cases for kNN include: Relevance ranking based on natural language processing (NLP) algorithms Product recommendations and recommendation engines Similarity search for images or videos Prerequisites edit
