A Critical Look at Recent Trends in Compression of Channel State Information

ICASSP 2023accepted

In this paper, we challenge the current view on state-of-the-art deep learning-based methods for compressing wireless channel state information and show that traditional methods can be highly competitive on commonly used open-source benchmarks. We show that basic signal processing methods can offer…

Accurate Optimization of Weighted Nuclear Norm for Non-Rigid Structure from Motion

ECCV 2020poster

Fitting a matrix of a given rank to data in a least squares sense can be done very effectively using 2nd order methods such as Levenberg-Marquardt by explicitly optimizing over a bilinear parameterization of the matrix. In contrast, when applying more general singular value penalties, such as weight…
