PPT-Performance of Nearest Neighbor

Queries in Rtrees Apostolos Papadopoulos and Yannis Manolopoulos Presenter Uma Kannan Contents Introduction Spatial data Management Research Spatial Access Methods Research. usthk Abstract A continuous nearest neighbor query retrieves the nearest neighbor NN of every point on a line segment eg find all my nearest gas stations during my route from point to point The result contains a set of point interval tuples such Neighbor. Search with Keywords. Abstract. Conventional spatial queries, such as range search and nearest . neighbor. retrieval, involve only conditions on objects' geometric properties. Today, many modern applications call for novel forms of queries that aim to find objects satisfying both a spatial predicate, and a predicate on their associated texts. For example, instead of considering all the restaurants, a nearest . MA4102 – Data Mining and Neural Networks. Nathan Ifill. ngi1@le.ac.uk. University of Leicester. Image source: . Antti. .
