Re: [Lshkit-users] A question about the Matrix

[Dongbo W. <don...@gm...>]

Wei,

Thanks for your quick reply! The dataset I use now are all stored in the
database, so yes, I need to implement my accessor class. But what I planed
to do is to extend the Matrix class and overload the load/save methods.
Thanks for your clarification.

I'll let your know if I have any other questions.

Best,
Dongbo

Re: [Lshkit-users] A question about the Matrix

[Wei D. <wdong@CS.Princeton.EDU>]

Dongbo,

For file format, see this page: 
http://lshkit.sourceforge.net/dc/d46/matrix_8h.html .
The source of matrix load/save methods are in 
lshkit/include/lshkit/matrix-io.h.
The LSH index actually depends only on the Accessor interface, which 
retrieves feature vector according to key value.  If you have your own 
data storage format, I encourage you to implement your own accessor 
class following the interface of Matrix::Accessor as defined in 
lshkit/include/lshkit/matrix.h .

Have fun.

[Lshkit-users] A question about the Matrix

[Dongbo W. <don...@gm...>]

Hi,

I'm trying to use LSHKIT on a content-based image retrieval project. I have
a question about the functions related to file operations in Matrix. I
cannot find the source code of load and save, so how should I arrange the
format of dataset if I want to use load, save directly? What exactly is the
format of the audio sample dataset?

Thanks!
Dongbo
