An approximate nearest neighbor search algorithm is allowed to return points whose distance from the query is at most times the distance from the query to its nearest points. The appeal of this approach is that, in many cases, an approximate nearest neighbor is almost as good as the exact one. Visa mer Nearest neighbor search (NNS), as a form of proximity search, is the optimization problem of finding the point in a given set that is closest (or most similar) to a given point. Closeness is typically expressed in terms of a … Visa mer Various solutions to the NNS problem have been proposed. The quality and usefulness of the algorithms are determined by the time complexity of queries as well as the space complexity of any search data structures that must be maintained. The … Visa mer • Ball tree • Closest pair of points problem • Cluster analysis Visa mer The nearest neighbour search problem arises in numerous fields of application, including: • Pattern recognition – in particular for optical character recognition • Statistical classification – see k-nearest neighbor algorithm Visa mer There are numerous variants of the NNS problem and the two most well-known are the k-nearest neighbor search and the ε-approximate nearest neighbor search. k-nearest neighbors Visa mer • Shasha, Dennis (2004).
