Frequency principle: Fourier analysis sheds light on deep neural networks

ZQJ Xu, Y Zhang, T Luo, Y Xiao, Z Ma - arXiv preprint arXiv:1901.06523, 2019 - arxiv.org
We study the training process of Deep Neural Networks (DNNs) from the Fourier analysis
perspective. We demonstrate a very universal Frequency Principle (F-Principle)---DNNs …
