W4A2 - Normalization term inconsistency

In week 4 assignment 2 (“Art_Generation_with_Neural_Style_Transfer”), section 4.1.2 contains a content loss equation

The normalization term (1/4…) seems to be different than the one described in the lecture video and also the original paper, which uses "1/2”.

Practically speaking, the value of constant didn’t make big difference as we would scale the cost with another hyperparameter anyway. However, I would love to know what is the “correct” constant value for the content cost equation and how the term was derived.

Hi there, as you said

Therefore, I think both 1/2 and 1/4 are acceptable.
