How can I get a dimensionality reduction matrix for my data?
Below, the dll of our TBI system and the corresponding help document are
available for download. All codes are complied with Microsoft VS
2005 in Windows XP. We have also tested the usability of the dll
file under the IDE of Microsoft VS 2008 and Microsoft VS 2010. To
understand the core technology of TBI system, please refer to the
before-mentioned technical report.
Efficient EMD-based similarity search in multimedia databases via flexible dimensionality reduction, SIGMOD 08: 199-212.
Why the TBI search results do not match the linear scan results?
Check if you have used the same ground
distance (e.g., Euclidean distance) during the process of feasible
solution file generation and the process of TBI running. That is to say,
if you use the Euclidean distance-based feasible solution file, you
have to set the ground distance as Euclidean distance in the file parameter.h. Otherwise, some results will get lost.
- What is the largest histogram dimensionality and database cardinality TBI system can support?
The largest histogram dimensionality and
database cardinality the recent version of TBI can support are 250 and
500,000. If you need a larger histogram dimensionality of database
cardinality to support your application, please don't hesitate to
