Output and compatibility of Skip-Encoder.ipynb

[leon-bungert]

The run specification in block [11] should be checked. Furthermore, output shouldn't contain accuracies for a denoising task.

[TimRoith]

The previous skip-encoder notebook was not updated properly and was therefore not compatible with the major update
9e4a080697cad49011db71fda334d97f43d18be9.

The correct file was pushed in 3f3667b61eaaff7c56c5da705d28ffb11eda1928.

The accuracy output issue remains. Furthermore the notebook should provide the pictures from the paper.
