To understand how multipoint queries and arbitrary distance functions
(e.g., arbitrary Lp metric with arbitrary weight along each dimension)
are handled in the hybrid tree, please read sections 2 and 3 of the paper
on query refinement .
To run query refinement on top of hybrid tree, download
this code. The code contains
a README_relfeed file that describes
how to run the code along with the hybrid tree code. Note that
the refinement code would not work unless you have downloaded the
hybrid tree code (from above).
Among others, the hybrid tree code is being used by:
Prof. Hyo Jong Lee and his students at Chonbuk National University in Korea
Dave Thomas at AdInjection.com for a project in his company
Dr. Progress Q. T. Mtshali for student projects
data mining class at the Nova Southeastern University .
Devasis Bassu at Telcordia Technologies
Huang Wu at the National University of Singapore for his research work
OuYang WeiMin at Anhui University, China for research
Dang Tran Khanh at Johannes Kepler Universitšt Linz
Database Lab at University of California at Riverside for research
