I am not @lxm-001 , but here is how I parsed their question:

There are some images that I got by applying various augmentation steps to images which are present in the training data. Is it OK to use such images (which I got by augmenting the “real” training data) as inputs to my validation step as well, or should validation be done entirely on “real” training data?

Perhaps they meant to ask something else, though!
