Web20 sep. 2016 · Unless there is a data specific reason, the mini-batch for neural net training is always drawn without replacement. The idea is you want to be somewhere in between the batch mode, which calculates the gradient with the entire dataset and SGD, which uses just one random. – horaceT Sep 20, 2016 at 20:47 Web13.6 Stochastic and mini-batch gradient descent. In [1]: In this Section we introduce two extensions of gradient descent known as stochastic and mini-batch gradient descent which, computationally speaking, are significantly more effective than the standard (or batch) gradient descent method, when applied to large datasets.
