Coded fourier transform

open access: yes2017 55th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2017
We consider the problem of computing the Fourier transform of high-dimensional vectors, distributedly over a cluster of machines consisting of a master node and multiple worker nodes, where the worker nodes can only store and process a fraction of the inputs.

Inverted Residual Fourier Transformation for Lightweight Single Image Deblurring

open access: yesIEEE Access, 2023
Single image deblurring aims to restore a sharp image by removing blurred areas in the single image. Such blurred images are not only visually unpleasant, but cause various problems in many applications like image recognition.

The Graphon Fourier Transform [PDF]

open access: yesICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020
In many network problems, graphs may change by the addition of nodes, or the same problem may need to be solved in multiple similar graphs. This generates inefficiency, as analyses and systems that are not transferable have to be redesigned. To address this, we consider graphons, which are both limit objects of convergent graph sequences and random ...
