Frequency Principle: Fourier Analysis Sheds Light on Deep Neural Networks

Communications in Computational Physics, 2019
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 often fit target functions from low to high frequencies --- on high-dimensional

Fractional Fourier Analysis Using the Möbius Inversion Formula

IEEE Transactions on Signal Processing, 2019
Compared with the Fourier analysis, the fractional Fourier analysis is more suitable to process linear frequency modulation type non-stationary functions.

Fourier Analysis and Fourier Transform

2017
The origins of Fourier analysis in science can be found in Ptolemy’s decomposing celestial orbits into cycles and epicycles and Pythagoras’ decomposing music into consonances. Its modern history began with the eighteenth century work of Bernoulli, Euler, and Gauss on what later came to be known as Fourier series. J.

Single-Image Depth Estimation Based on Fourier Domain Analysis

2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018
We propose a deep learning algorithm for single-image depth estimation based on the Fourier frequency domain analysis. First, we develop a convolutional neural network structure and propose a new loss function, called depth-balanced Euclidean loss, to ...
