I'm trying to use Eigen recognizer in C++ code and it looks oddly for me, please correct my dev logic if it's wrong : example scenario:
- there is a database of the photos with user ids (more than one photo per user id)
- I'm training the recognizer with e.g. user id = 29 (5 photos), and user id = 2 (4 photos), so input vectors are:
29 - 1th user's photo1
29 - 1th user's photo2
29 - 1th user's photo3
29 - 1th user's photo4
29 - 1th user's photo5
2 - 2th user's photo1
2 - 2th user's photo2
2 - 2th user's photo3
2 - 2th user's photo4
for the testing only , I'm using first photo of user id = 2 as input
the results looks oddly : confidence = ~40.000, but label = 29 (supposed 2 as user_id during the training in labels vector)
what is wrong in such logic?
thank you
