In 01_simple_nn.ipynb, there should be fit_transform instead of only transform

In the last line of the 2nd coding cell of 15_deep_learning_with_tensorflow/01_simple_nn.ipynb, In my opinion there should be fit_transform instead of just transform.

if u fit transform on x test, you will cause data leakage bcz the model will also peek from x test
