![]() Various solutions to the NNS problem have been proposed. Cluster analysis – assignment of a set of observations into subsets (called clusters) so that observations in the same cluster are similar in some sense, usually based on Euclidean distance.Similarity scores for predicting career paths of professional athletes.Spell checking – suggesting correct spelling.Internet marketing – see contextual advertising and behavioral targeting.Coding theory – see maximum likelihood decoding.Computational geometry – see Closest pair of points problem.Computer vision – for point cloud registration.Statistical classification – see k-nearest neighbor algorithm.Pattern recognition – in particular for optical character recognition.The nearest neighbour search problem arises in numerous fields of application, including: One example is asymmetric Bregman divergence, for which the triangle inequality does not hold. However, the dissimilarity function can be arbitrary. Even more common, M is taken to be the d-dimensional vector space where dissimilarity is measured using the Euclidean distance, Manhattan distance or other distance metric. Most commonly M is a metric space and dissimilarity is expressed as a distance metric, which is symmetric and satisfies the triangle inequality. A direct generalization of this problem is a k-NN search, where we need to find the k closest points. 3 of The Art of Computer Programming (1973) called it the post-office problem, referring to an application of assigning to a residence the nearest post office. Closeness is typically expressed in terms of a dissimilarity function: the less similar the objects, the larger the function values.įormally, the nearest-neighbor (NN) search problem is defined as follows: given a set S of points in a space M and a query point q ∈ M, find the closest point in S to q.
