> The SGLD optimizer adds random Gaussian noise to the weights updates. If no seed is set, every update of the optimizer will produce different noise. In cases where you would like to be able to replicate the updates (research studies, tests), setting a seed to control the noise generation is useful. 
>  
> Test is added for the SGLD optimizer considering the noise replication.
>  
> A comment is added to the SGLD docstring about noise replication.
