This is a really great introductory video on Keras and how simple it makes calling complex deep learning libraries like Tensorflow. The 13 year old author builds a great deep learning model in under 100 lines of code.
I do some questions w.r.t. to the AUC score being 1 (that always raised red flags in my mind) but he he does share the code on Github so everyone can follow along.
This is why I like Keras a lot, it's like H2O.ai and makes the complex work of coding very simple and accessible.
