"WebAn epoch is defined as one cycle through the training data. It is not an epoch, if you fix the number of steps. Analogically you can't call it epoch, if you sample the training example independently in each step. You can save your checkpoint and do checks every N Steps, but this does not mean that N Steps become an epoch. " - Epoch meaning in data science
