machine learning - how to use iter_size in caffe - Stack …

https://stackoverflow.com/questions/45748744/how-to-use-iter-size-in-caffe

I dont know the exact meaning of 'iter_size' in caffe solver though I googled a lot. it always says that 'iter_size' is a way to effectively increase the batch size without requiring the extra GPU memory. If set bach_size=10,iter_size=10, its behavior is the same as batch_size = 100.
