continuous time version because that's the one that is easier to analyze so what about stochastic gravities so first of all a reminder was what's stochastic it's you know the same thing but we are taking the samples one by one so when we say stochastic writing decent in the literature we mean usually one of the two following things so either we mean the online stochastic grading descent where each iteration uses a fresh sample and never uses a sample that was ever seen before and i like to call it online stochastic
