Parallelizable Riemannian Alternating Direction Method of Multipliers for Non-convex Pose Graph Optimization
Xin Chen, Chunfeng Cui, Deren Han +1
Pose graph optimization (PGO) is fundamental to robot perception and navigation systems, serving as the mathematical backbone for solving simultaneous localization and mapping (SLA…
A Single-loop Proximal Subgradient Algorithm for A Class Structured Fractional Programs
Deren Han, Min Tao, Zihao Xia
In this paper, we investigate a class of nonconvex and nonsmooth fractional programming problems, where the numerator composed of two parts: a convex, nonsmooth function and a diff…
An Accelerated Alternating Partial Bregman Algorithm for ReLU-based Matrix Decomposition
Qingsong Wang, Yunfei Qu, Chunfeng Cui +1
Despite the remarkable success of low-rank estimation in data mining, its effectiveness diminishes when applied to data that inherently lacks low-rank structure. To address this li…
Fair Primal Dual Splitting Method for Image Inverse Problems
Yunfei Qu, Deren Han
Image inverse problems have numerous applications, including image processing, super-resolution, and computer vision, which are important areas in image science. These application…
