Nearest neighbor search (NNS), also known as proximity search,similarity search orclosest point search, is an optimization problem for finding closest (or most similar) points. Closeness is typically expressed in terms of a dissimilarity function: The less similar are ...

Building an index tree is a common approach to speed up the k nearest neighbour search in large databases of many-dimensional records. Many applications require varying distance metrics by putting a weight on different dimensions. The main problem with k nearest neighbour searches using weighted ...
The essence of approximate nearest neighbour search consists in roughly dividing the search space into a number of buckets that contain points that are close to each other, and then only looking within a given bucket when performing a search. This gives us speed (we only have to scan the con...

The nearest neighbour (NN) rule is widely used in pattern recognition tasks due to its simplicity and its good behaviour. Many fast NN search algorithms have been developed during last years. However, in some classification tasks an exact NN search is too slow, and a way to quicken the sear...
