How does batch size affect stochastic gradient descent?

WebFor a batch size of 10 vs 1 you will be updating the gradient 10 times as often per epoch with the batch size of 1. This makes each epoch slower for a batch size of 1, but more updates are being made. Since you have 10 times as many updates per epoch it can get to a higher accuracy more quickly with a batch size or 1. WebFeb 17, 2024 · However, it is perfectly fine if I try to set batch_size = 32 as a parameter for the fit() method: model.fit(X_train, y_train, epochs = 5, batch_size = 32) Things get worst when I realized that, if I manually set batch_size = 1 the fitting process takes much longer, which does not make any sense according to what I described as being the algorithm.
