Question about the batch size

[cygbbhx]

Hi, I am trying to reproduce your training results and have a question about the batch size.
From the paper, I see

During the training phase, we set the batch size to 128 ...
We set the number of total epochs to 200, each of which had 512 randomly selected mini-batches.

After running the preprocessing, I get total around 32 * 720 * 5 = 115200 images.
By mini-batches, do you mean you used random 512 batches per epoch, each size of 128?
