Instead of using all training data items to compute gradients (as in batch training) or using a single training item to compute gradients (as in stochastic training), mini-batch training uses a user-specified number of training items. In pseudo-code, mini-batch training is:

WebI am training a neural network on google colab. I tried mini batch size of 64. It took approx 24 minutes to complete one epoch. Also 600 MB of GPU RAM was occupied out of 15 GB. Next I tried mini batch size of 2048 and it still take approx 24 minutes to complete one epoch with 3.6 GB of GPU RAM occupied. Shouldnt it execute faster? WebTo 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. pruritus is what https://chiswickfarm.com
