About this site

Apr 27, 2018  Batch size is an important hyper-parameter for Deep Learning model training. When using GPU accelerated frameworks for your models the amount of memory available on the GPU is a limiting factor. In this post I look at the effect of setting the batch size for a few CNN's running with TensorFlow on 1080Ti and Titan V with 12GB memory, and GV100 with 32GB memory.

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.
