A vantage-point tree (or VP tree) is a metric tree that segregates data in a metric space by choosing a position in the space (the "vantage point") and partitioning the data points into two parts: those points that are nearer to the vantage point than a threshold, and those points that are not.
Vantage Point Trees (VP-Trees) are a type of data structure used for efficiently searching for nearest neighbors in metric spaces. They are particularly useful in machine learning, computer vision, and information retrieval tasks, where finding the closest data points to a query point is a common operation.
Vantage Point Tree (or vp tree) is a space partitioning data structure that allows for efficient querying of nearest neighbors in high dimensional spaces. Implementation. The code is based on a great tutorial: http://stevehanov.ca/blog/index.php?id=130 I modified it so that the search routine can be run in parallel.
Un VPT es un árbol binario en el que cada nodo representa un subconjunto S de individuos del conjunto inicial, utiliza un elemento especial del conjunto llamado pivote (vantage point) para dividir el conjunto S en dos subconjuntos, uno por cada hijo.
The proposed algorithm uses Vantage-Point-Trees to provide fast nearest neighbor search result-ing in optimal single-linkage clustering with time complexity O(Nlog2N). We offer adjustments to the algorithm that reduce the time complexity to O(NlogN), but we lose the guarantee of optimal clustering.
3 de feb. de 2016 · Vantage point tree (VPT) [8, 9] is an indexing tree for similarity search in metric space. It only exploits one pivot for each index node. According to the pivot space model [ 7 ], with one pivot, data is mapped into a one-dimensional pivot space.
vp-tree. A vantage point tree implementation in OCaml. Cf. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.41.4193&rep=rep1&type=pdf for details. A vantage point tree allows to do fast but exact nearest neighbor searches in any space provided that you have a distance function to measure the distance between any two points in that space.
