Convergence analysis of the Riemannian proximal gradient method with inexact oracle
Chao Huang, Xiyuan Xie, Anna Qi +2
We extend the notion of an inexact first-order oracle from the Euclidean setting to Riemannian optimization, and conduct a convergence analysis for the Riemannian proximal gradient…
A proximal algorithm incorporating difference of convex functions optimization for solving a class of single-ratio fractional programming
Anna Qi, Jianfeng Huang, Lihua Yang +1
In this paper, we consider a class of single-ratio fractional minimization problems, where both the numerator and denominator of the objective are convex functions satisfying posit…
Power-Series Approach to Moment-Matching-Based Model Reduction of MIMO Polynomial Nonlinear Systems
Chao Huang, Alessandro Astolfi
The model reduction problem for high-order multi-input, multi-output (MIMO) polynomial nonlinear systems based on moment matching is addressed. The technique of power-series decomp…
Atomic Filter: a Weak Form of Shift Operator for Graph Signals
Lihua Yang, Qing Zhang, Qian Zhang +1
The shift operation plays a crucial role in the classical signal processing. It is the generator of all the filters and the basic operation for time-frequency analysis, such as win…
Graph Fourier Transform Based on Norm Variation Minimization
Lihua Yang, Anna Qi, Chao Huang +1
The definition of the graph Fourier transform is a fundamental issue in graph signal processing. Conventional graph Fourier transform is defined through the eigenvectors of the gra…
