@OmriKaduri here is my understanding: Assume the sigma in the original paper is x, and sigma in the code is y, then we will have log(x)=0.5y, then x=e^(0.5y). After that, taking x=e^(0.5y) into the original formulation, x^(-2) will become e^(-y), so the original formulation: x^(-2)loss+log(x) will become: e^(-y)loss+0.5y
Hi, at your loss function you calculate:
Where
sem_uncertainty
should be the log variance of the semantic segmentation task, but why do you multiply it by 0.5?As can be seen in the original paper, there is no divsion of that component:![image](https://user-images.githubusercontent.com/7421460/98551469-03e22580-22a6-11eb-8ab0-6ca2023d96d4.png)
