Effects of Batch-normalization on Fisher Information Matrix of ResNet
Yasutaka Furusho, Kazushi Ikeda (NAIST) IBISML2018-110
Abstract (in Japanese) (See Japanese page) 
(in English) ResNet have intensively been studied and many techniques have been used for better performance.
Batch-normalization (BN) is one of these techniques, which accelerates convergence of training ResNet.
To clear its acceleration mechanism, we analyzed how BN affects the loss landscape, in particular, the eigenvalues of the Fisher information matrix of ResNet.
Our results show that the ResNet has eigenvalues that grow exponentially with its depth,
and that the ResNet with BN has eigenvalues that grow sub-linear with its depth.
These imply that BN allows the ResNet to use larger learning rate and hence converges faster than the vanilla ResNet.
