In this paper, we establish a unified framework to study the almost sure global convergence and the expected convergence rates of a class of mini-batch stochastic (projected) gradient (SG) methods, including two popular types of SG:stepsize diminishedSG andbatch size increasedSG. We also show that the standard variance uniformly bounded assumption, which is frequently used in the literature to investigate the convergence of SG, is actually not required when the gradient of the objective function is Lipschitz continuous. Finally, we show that our framework can also be used for analyzing the convergence of a mini-batch stochastic extragradient method for stochastic variational inequality.
