batch size vs learning rate
Why do we increase batch size during training?
instead of decaying the learning rate, we increase the batch size during training. This strategy achieves near-identical model performance on the test set with the same number of training epochs but significantly fewer parameter updates.
Should batch size be multiplied by K?
Theory suggests that when multiplying the batch size by k, one should multiply the learning rate by sqrt (k) to keep the variance in the gradient expectation constant. See page 5 at A. Krizhevsky.
Why is a small batch better than a large batch?
To conclude, and answer your question, a smaller mini-batch size (not too small) usually leads not only to a smaller number of iterations of a training algorithm, than a large batch size, but also to a higher accuracy overall, i.e, a neural network that performs better, in the same amount of training time, or less.
Does batch size affect learning rate?
For reference, I was discussing with someone, and it was said that, when batch size is increased, the learning rate should be decreased by some extent. My understanding is when I increase batch size, computed average gradient will be less noisy and so I either keep same learning rate or increase it.
