A Robust EDM Optimization Approach for 3D Single-Source Localization with Angle and Range Measurements
Mingyu Zhao, Qingna Li, Hou-Duo Qi
The paper proposes a robust Euclidean distance matrix optimization method that jointly uses range and angle data with an L1-norm criterion to improve 3D single-source localization…
On Constraint Qualifications for MPECs with Applications to Bilevel Hyperparameter Optimization for Machine Learning
Jiani Li, Qingna Li, Alain Zemkoho
Constraint qualifications for a Mathematical Program with Equilibrium Constraints (MPEC) are essential for analyzing stationarity properties and establishing convergence results. I…
TrasMuon: Trust-Region Adaptive Scaling for Orthogonalized Momentum Optimizers
Peng Cheng, Jiucheng Zang, Qingnan Li +6
Muon-style optimizers leverage Newton-Schulz (NS) iterations to orthogonalize updates, yielding update geometries that often outperform Adam-series methods. However, this orthogona…
Fast Algorithms for Optimal Damping in Mechanical Systems
Qingna Li, Françoise Tisseur
Optimal damping aims at determining a vector of damping coefficients that maximizes the decay rate of a mechanical system's response. This problem can be formulated as the min…
Modified Block Newton Algorithm for -Regularized Optimization
Yuge Ye, Qingna Li
In this paper, we propose a globally convergent Newton type method to solve regularized sparse optimization problem. In fact, a line search strategy is applied to the Newt…
Proximal Iterative Hard Thresholding Algorithm for Sparse Group -Regularized Optimization with Box Constraint
Yuge Ye, Qingna Li
This paper investigates a general class of problems in which a lower bounded smooth convex function incorporating and regularization is minimized over a box…
