[Kdn-users] demo notebook

Hello, I am a student, and I am trying to recreate the paper, to see the results I have tried to use the notebook that you provided, there is something that I don't understand, I see that you are normalizing the delay and traffic in the parse, and after you get the predictions you are normalizing them using: predctions = 0.54*preds + 0.37 why is that? and if I want to predict the jitter for example do I need to train another network with the labels being jitter? thank you Ayman Khiralden
