About val.txt

[WindVChen]

Hi,

I recently did some research on fine-grained classification, and I find that there are only train.txt and test.txt in your directory 'dataset'. Is the 'val.txt' in the code actually the 'test.txt'? Whether should I split trainset into train and val set when I do some experiments on datasets like CUB_200_2011, since I also didn't find any description about validation set in other existing papers?

Thank you.

Kind regards.
