asynchronous stochastic gradient descent for dnn training

... alternative approach to training a log-linear model is to use stochastic gradient descent (SGD) methods. SGD uses approximate gradients esti- mated from subsets of the training data and up- dates ... (2) 3 Stochastic Gradient Descent SGD uses a small randomly-selected subset of the training samples to approximate the gradient of the objective function given by Equation 2.
