3.1 REVISITING EUCLIDEAN NORMALIZATION

In Euclidean DNNs, normalization stands as a pivotal technique for accelerating network training by mitigating the issue of internal covariate shift (Ioffe & Szegedy, 2015). While various normalization methods have been introduced (Ioffe & Szegedy, 2015; Ba et al., 2016; Ulyanov et al., 2016; Wu & He, 2018), they all share a common fundamental concept: the regulation of the first and second statistical moments. In this paper, we focus on batch normalization only.
