Batch Size in a Neural Network explained - deeplizard

Put simply, the batch size is the number of samples that will be passed through to the network at one time. Note that a batch is also commonly referred to as a mini-batch. The batch size is the number of samples that are passed to the network at once. Now, recall that an epoch is one single pass over the entire training set to the network.

How to Measure Inference Time of Deep Neural Networks Deci

May 04, 2020  To find the optimal batch size, a good rule of thumb is to reach the memory limit of our GPU for the given data type. This size of course depends on the hardware type and the size of the network. The quickest way to find this maximal batch size is by performing a binary search. When time is of no concern a simple sequential search is sufficient.
