Dynamically Optimizing High-Dimensional Index Structures [chapter]

Christian Böhm, Hans-Peter Kriegel
2000 Lecture Notes in Computer Science  
In high-dimensional query processing, the optimization of the logical page-size of index structures is an important research issue.  ...  Therefore, we propose a method for adapting the page size of an index dynamically during insert processing.  ...  Conclusion In this paper, we have proposed a dynamic optimization technique for multidimensional index structures.  ...

A dynamic insertion approach for multi-dimensional data using index structures

Yong Shi
2009 Proceedings of the 47th Annual Southeast Regional Conference on - ACM-SE 47  
To improve the performance of this index structure, we propose a dynamic insertion approach for time-related multi-dimensional data based on a modified ClusterTree + , keeping the index structure always  ...  Nowadays large volumes of data with high dimensionality are being generated in many fields. Most existing indexing techniques degrade rapidly when dimensionality goes higher.  ...  At the leaf level, the first leaf node has three data entries DYNAMIC INSERTION TO CLUSTERTREE + Dynamic insertion of high dimensional data becomes a critical issue in real high dimensional databases  ...

A Flexible Dynamic Data Structure for Scientific Computing [chapter]

Josef Weinbub, Karl Rupp, Siegfried Selberherr
2013 Lecture Notes in Electrical Engineering  
We present an approach for a generic, multi-dimensional run-time data structure suitable for high-performance scientific computing in C++.  ...  High-performance, multi-dimensional data access is realized by utilizing a heterogenous compile-time container generation function.  ...  A typical challenge is to provide a high-performing, dimension agnostic access mechanism, as a utilization of a dynamic container for the index-tuple, which does not result in poor performance due to run-time  ...

An adaptive and dynamic dimensionality reduction method for high-dimensional indexing

Heng Tao Shen, Xiaofang Zhou, Aoying Zhou
2005 The VLDB journal  
The notorious "dimensionality curse" is a wellknown phenomenon for any multi-dimensional indexes attempting to scale up to high dimensions.  ...  In this paper, we present an adaptive Multi-level Mahalanobisbased Dimensionality Reduction (MMDR) technique for high-dimensional indexing.  ...  To index the reduced subspaces, a Global indexing structure [4] was introduced, which consists of separate high-dimensional indices for every subspace.  ...

UB-Tree Based Efficient Predicate Index with Dimension Transform for Pub/Sub System [chapter]

Botao Wang, Wang Zhang, Masaru Kitsuregawa
2004 Lecture Notes in Computer Science  
In this paper, considering dynamic maintenance and space efficiency of publish/subscribe system, we propose an index structure for event filtering based on UBtree.  ...  There, by dimension transform, the event filtering is regarded as high dimensional range query. The feasibility of the proposed index is evaluated in simulated publish/subscription environment.  ...  It is a dynamic index structure based on B-tree and supports updates with logarithmic performance like B-tree with space complexity O(n).  ...
