Hi there Ozair,
It's actually a bad idea for debugging and reproducibility to set the seed. Setting the seed (preferably by calling `math::RandomSeed()`, but the Armadillo function you mentioned works too) should be done at a higher level than SGD. If the seed is set inside of the SGD class, then if I have a bug that I am trying to track down, it becomes very hard if I can't easily set the seed to one specific value (or leave it as the default). If anything it may be worth adding a bit to the documentation or one of the tutorials (probably a tutorial is the better place) noting that it might be useful to set the random seed at a higher level.
