ESVM with HMAX Features

[ium121]

Hi

I have been trying to replace HOG with HMAX features in the ESVM framework.
When I do the training with HMAX features I get the following error
"ERROR: number of negative support vectors is 0!
Something went wrong"

Can you explain what might be the cause for this error?

Thanks

@ium121, I can advice you to dig into the exemplarsvm/internal/esvm_update_svm.m (this file contains the line with this error) and try to find out why libSVM not learning. Try to look what arguments you call libsvmtrain(...) with, may be it will help to debug.
