An Efficient Cost Model for Optimization of Nearest Neighbor Search in Low and Medium Dimensional Spaces
Found in: IEEE Transactions on Knowledge and Data Engineering
By Yufei Tao, Jun Zhang, Dimitris Papadias, Nikos Mamoulis
Issue Date:October 2004
pp. 1169-1184
Existing models for nearest neighbor search in multidimensional spaces are not appropriate for query optimization because they either lead to erroneous estimation or involve complex equations that are expensive to evaluate in real-time. This paper proposes...
 
A Unified Approach to Streamline Selection and Viewpoint Selection for 3D Flow Visualization
Found in: IEEE Transactions on Visualization and Computer Graphics
By Jun Tao, Jun Ma, Chaoli Wang, Ching-Kuang Shene
Issue Date:March 2013
pp. 393-406
We treat streamline selection and viewpoint selection as symmetric problems which are formulated into a unified information-theoretic framework. This is achieved by building two interrelated information channels between a pool of candidate streamlines and ...
 
SkipMard: A Multi-attribute Peer-to-Peer Resource Discovery Approach
Found in: Computer and Computational Sciences, International Multi-Symposiums on
By Tao He, Jun Ni, Alberto M Segre, Shaowen Wang, Boyd M.Knosp
Issue Date:August 2007
pp. 266-273
Resource discovery technologies for Grids and Peer-to-Peer (P2P) systems share some characteristics. However, some P2P systems such as Skip Graph cannot simply be applied to Grid resource discovery because complex grid resources need to be searched by usin...

This paper demonstrates a heterogeneous windows cluster system to obtain high performance computing (HPC) resources for medical image reconstruction applications. The communication in the cluster system is powered by MPICH open source library. Our works ar...
 
Modeling user's preference in folksonomy for personalized search
Found in: Cloud and Service Computing, International Conference on
By Zhaowen Tao,Jun Hu,Wei He,RunSheng Li,Deyi Li
Issue Date:December 2011
pp. 55-59
Personalized search based on the users' preference has been extensively studied in the field of information retrieval. As a typical representative of web2.0, social tagging not only allows users to better describe and manage web resources, but also provide...
 
An Energy-Balanced Multicast Routing Algorithm in Wireless Sensor Networks
Found in: Grid and Cloud Computing, International Conference on
By Wang Fangfang, Tao Jun, Shao Birui
Issue Date:November 2010
pp. 361-365
An energy-balanced multicast routing algorithm EBMR in wireless sensor networks (WSNs) is proposed. The objective of EMBR algorithm is to improve the energy efficiency and extend the network lifetime in multicast. To achieve this goal, the energy consumpti...
