High dimensional nearest neighbor searching
, 2006
"... As databases increasingly integrate different types of information such as timeseries, multimedia and scientific data, it becomes necessary to support efficient retrieval of multidimensional data. Both the dimensionality and the amount of data that needs to be processed are increasing rapidly. As ..."

. VA þfile is especially useful for searching exact nearest neighbors (NN) in nonuniform high dimensional data sets. We then discuss how to improve the search and make it progressive by allowing some approximations in the query result. We develop a general framework for approximate NN queries
Multilevel Filtering for High Dimensional Nearest Neighbor Search
 In proceedings of ACM SIGMOD Workshop on Research Issues in Data Mining and Knowledge
, 2000
"... Searching for nearest neighbors among a large number of vectors in a high dimensional space is usually costly and timeconsuming. To support such high dimensional nearest neighbor searches, low dimensional approximations of vectors are usually used to filter out many vectors (and hence to reduce the ..."

Quality and Efficiency in High Dimensional Nearest Neighbor Search
"... Nearest neighbor (NN) search in high dimensional space is an important problem in many applications. Ideally, a practical solution (i) should be implementable in a relational database, and (ii) its query cost should grow sublinearly with the dataset size, regardless of the data and query distributi ..."

Towards Meaningful HighDimensional Nearest Neighbor Search by HumanComputer Interaction
 In ICDE
, 2002
"... Nearest Neighbor search is an important and widely used problem in a number of important application domains. In many of these domains, the dimensionality of the data representation is often very high. Recent theoretical results have shown that the concept of proximity or nearest neighbors may not b ..."

Lower bounds for high dimensional nearest neighbor search and related problems
, 1999
"... In spite of extensive and continuing research, for various geometric search problems (such as nearest neighbor search), the best algorithms known have performance that degrades exponentially in the dimension. This phenomenon is sometimes called the curse of dimensionality. Recent results [38, 37, 40 ..."

Adaptively Discovering Meaningful Patterns in HighDimensional Nearest Neighbor Search
, 2003
"... To query highdimensional databases, similarity search (or k nearest neighbor search) is the most extensively used method. However, since each attribute of high dimensional data records only contains very small amount of information, the distance of two highdimensional records may not always corr ..."

"... Consider a dataset of n(d) points generated independently from Rd according to a common p.d.f. fd with support(fd) = [0, 1] d and sup{fd([0, 1] d)} growing subexponentially in d. We prove that: (i) if n(d) grows subexponentially in d, then, for any query point ⃗q d ∈ [0, 1] d and any ǫ> 0, the ..."

The SRtree: An Index Structure for HighDimensional Nearest Neighbor Queries
, 1997
"... Recently, similarity queries on feature vectors have been widely used to perform contentbased retrieval of images. To apply this technique to large databases, it is required to develop multidimensional index structures supporting nearest neighbor queries e ciently. The SStree had been proposed for ..."
