they are default in train.lua
i try using the same hyperparameters and the errors i get are huge. I replicated the code in theano. and with sgd and learning rate 1 it cannot learn anything at all.

Are you sure the initial LR is 1?
Same thing happens when I rewrite this model in Pytorch. But I train models with RGB images, does this effect the training a lot?
What hyperparameters do you use for training the best-performing VGG+BN+dropout model?
