WebJan 22, 2024 · Non-stochastic gradient descent involves making exactly one update per epoch. True stochastic gradient descent makes progress considerably faster because it makes one update per input sample. A common compromise is to split the data into batches and make one update per batch. WebDec 15, 2024 · I'm trying to implement a version of differentially private stochastic gradient descent (e.g., this ), which goes as follows: Compute the gradient with respect to each point in the batch of size L, then clip each of the L gradients separately, then average them together, and then finally perform a (noisy) gradient descent step.
