Convergence Analysis of Consensus-ADMM for General QCQP
Huiping Huang, Hing Cheung So, Abdelhak M. Zoubir
We analyze the convergence properties of the consensus-alternating direction method of multipliers (ADMM) for solving general quadratically constrained quadratic programs. We prove…
On Generalisation of Isotropic Central Difference for Higher Order Approximation of Fractional Laplacian
Pui Ho Lam, Hing Cheung So
The study of generalising the central difference for integer order Laplacian to fractional order is discussed in this paper. Analysis shows that, in contrary to the conclusion of a…
Nonlinear Tensor Ring Network
Xiao Peng Li, Qi Liu, Hing Cheung So
The state-of-the-art deep neural networks (DNNs) have been widely applied for various real-world applications, and achieved significant performance for cognitive problems. However,…
Arbitrary order of convergence for Riesz fractional derivative via central difference method
Pui Ho Lam, Hing Cheung So, Cheung Fat Chan
We propose a novel method to compute a finite difference stencil for Riesz derivative for artibitrary speed of convergence. This method is based on applying a pre-filter to the Grü…
TDOA-based localization with NLOS mitigation via robust model transformation and neurodynamic optimization
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So +3
This paper revisits the problem of locating a signal-emitting source from time-difference-of-arrival (TDOA) measurements under non-line-of-sight (NLOS) propagation. Many currently…
Image Denoising by Random Interpolation Average with Low-Rank Matrix Approximation
Qi Liu, Wing-Shan Tam, Chi-Wah Kok +1
With the wide deployment of digital image capturing equipment, the need of denoising to produce a crystal clear image from noisy capture environment has become indispensable. This…
