About the value of normVal #51

Hi, As said in the code that 'normalization value, as defined in ERFNet paper'. So I read the paper (Efficient Residual Factorized ConvNet for Real-time Semantic) , but I didn't find something about it. Then I went to see the source code of ERFNet, as shown below. The value of weight is fixed...Can you tell me more about the origin of this formula?Thank you

Check here:

ERFNets original code was written in lua and then translated to PyTorch. While translating, i assume they just extracted class imbalance weights from cached files in lua and used directly (I assume they did it to save time).
