چکیده

Applying standard dimensionality reduction techniques, we show how to perform approximate range searching in higher dimension while avoiding the curse of dimensionality. Given points in a unit ball in , an approximate halfspace range query counts (or reports) the points in a query halfspace; the qualifier “approximate” indicates that points within distance of the boundary of the halfspace might be misclassified. Allowing errors near the boundary has a dramatic effect on the complexity of the problem. We give a solution with query time and !#" $

Solving approximate similarity queries

As we know, both nearest neighbor and range searching problems are among the most important and fundamental problems in computational geometry because of its numerous important application areas [1, 2]. Specially, in many modern database applications, high-dimensional searching problems arise when complex objects are represented by vectors of d numeric features. As the dimension d increases hig...

Pii: S0925-7721(00)00022-5

The range searching problem is a fundamental problem in computational geometry, with numerous important applications. Most research has focused on solving this problem exactly, but lower bounds show that if linear space is assumed, the problem cannot be solved in polylogarithmic time, except for the case of orthogonal ranges. In this paper we show that if one is willing to allow approximate ran...

On Geometric Range Searching, Approximate Counting and Depth Problems

In this thesis we deal with problems connected to range searching, which is one of the central areas of computational geometry. The dominant problems in this area are halfspace range searching, simplex range searching and orthogonal range searching and research into these problems has spanned decades. For many range searching problems, the best possible data structures cannot offer fast (i.e., ...

Approximate Range Searching In The Absolute Error Model

Range searching is a well known problem in the area of geometric data structures. We consider this problem in the context of approximation, where an approximation parameter ε > 0 is provided, and points that are sufficiently close to the range’s boundary may or may not be included. Most prior work on approximating this problem has focused on the case of relative errors, in which it is assumed t...

Approximate Nearest Neighbor Queries among Parallel Segments

We develop a data structure for answering efficiently approximate nearest neighbor queries over a set of parallel segments in three dimensions. We connect this problem to approximate nearest neighbor searching under weight constraints and approximate nearest neighbor searching on historical data in any dimension and give efficient solutions for these as well.
