>From one novice to another ... 1. Yes, that is my understanding of how to run further iterations. 2. Yes, EPOCHS says to iterate that many times over your set of tests. I think I have heard the recommended number of EPOCHS in general is 2, though I don't know how much science is behind that. I

Re: [tesseract-ocr] Any success story?

The short answer is "no", but a fuller answer is that my use case is a bit different from others and is as follows ... I trained tesseract to read the MICR line at the bottom of bank checks using only 20K checks (i.e. real data, not synthetic). I was able to get 85% accuracy where the reason for
