Tesseract LSTM Training iterations information

[k.elta...@gmail.com]

I wasnt to ask about the information printed during training:

Loaded 83/1299 pages (2-84) of document train/features/this/features/eng.99903898.DejaVu_Sans_Mono_Bold.exp-2.lstmf

 what does 83/1299 and (2-84) means?

for that too

At iteration 3053/40000/40054, Mean rms=0.25%, delta=0.461%, char train=1.501%, word train=2.578%, skip ratio=0.2%,  wrote checkpoint.

what does 3053/400000/40054 means?

Another question what is the iteration batch size? so does an iteration implies going over all training data?
