negative examples

[ddemirdjian]

I would like to use negative examples (images of background containing none of the objects to detect). Is it possible to use such examples?

For negative examples, I captured background images and associated them with xml files containing no <object> tag.

• The ./convert script (in data/yolo) works fine
• The ./train script (in example/yolo) exits with the following error .... data_transformer.cpp:135] Check failed: float_size > 0 (0 vs. 0) Everysample must have label

Any idea or suggestion?

Negative examples are not supported in this repository.

Is there any reason or benefit to add negative examples?
