WebbThis is where the similarity search, or vector search, kicks in. Given a set of vectors and a query vector, we need to find the most similar items in our set for the query. We call this task nearest neighbor search. K Nearest Neighbors. K nearest neighbors or k-NN is WebbThe number of shared nearest neighbors is the intersection of the kNN neighborhood of two points. Note: that each point is considered to be part of its own kNN neighborhood. …
