Without the BN layer can performance well

[chaoyueziji]

Hello，When I was training the network, I did not add the BN layer, and the other structures were the same as the original. The training set used is only BSD40, and patch size is 40*40. In the test set12 on the PSNR is higher than the original, and the results from the loss convergence is also faster convergence than the BN layer.

You could put the quantitative results and the trained model for evaluation.

but my network does not converge when I remove BN，what's your resolution?please

Hmm, my network structure is Conv + relu + bn, so when I remove BN, I find it convergent and has similar performance. So at first I thought BN was an unnecessary module. My experiment result is to remove BN module and optimize it by Adam. When the noise level is 25, the result can reach 29.15.
