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. 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. .
