you can think of it really as data compression right you're compressing your data but and data compression is related to machine learning but it's not quite the same because data compression doesn't care about how do you perform on new images it only cares about how you compress the training images that you got and so what we propose to do is to think about this in terms of not data compression but data prediction to make the computer try to work harder and say instead of just compressing the data let's see if we can train it to
