A Homogeneous Tensor Framework for High-Order Trust-Region and Spherical Polynomial Optimization
Wenqi Zhu, Haibin Chen, Guanglu Zhou
High-order methods can improve worst-case evaluation complexity, but for orders their Taylor subproblems are nonconvex polynomial optimization problems and are generally d…
A Globally Convergent Third-Order Newton Method via Unified Semidefinite Programming Subproblems
Yubo Cai, Wenqi Zhu, Coralia Cartis +1
We propose the Adaptive Levenberg-Marquardt Third-Order Newton Method (ALM-TON) method for unconstrained nonconvex optimization; to our knowledge, the framework provides the first…
Recover Cell Tensor: Diffusion-Equivalent Tensor Completion for Fluorescence Microscopy Imaging
Chenwei Wang, Zhaoke Huang, Zelin Li +1
Fluorescence microscopy (FM) imaging is a fundamental technique for observing live cell division, one of the most essential processes in the cycle of life and death. Observing 3D l…
Sufficiently Regularized Nonnegative Quartic Polynomials are Sum-of-Squares
Wenqi Zhu, Coralia Cartis
A polynomial that is nonnegative need not be a sum of squares of polynomials. This classical gap, identified by Hilbert in 1888, lies at the heart of why the global optimization of…
Global Optimality Characterizations and Algorithms for Minimizing Quartically-Regularized Third-Order Taylor Polynomials
Wenqi Zhu, Coralia Cartis
High-order methods for convex and nonconvex optimization, particularly th-order Adaptive Regularization Methods (AR), have attracted significant research interest by naturall…
SoS1: O1 and R1-Like Reasoning LLMs are Sum-of-Square Solvers
Kechen Li, Wenqi Zhu, Coralia Cartis +2
Large Language Models (LLMs) have achieved human-level proficiency across diverse tasks, but their ability to perform rigorous mathematical problem solving remains an open challeng…
Tensor-based Dinkelbach method for computing generalized tensor eigenvalues and its applications
Haibin Chen, Wenqi Zhu, Coralia Cartis
In this paper, we propose a novel tensor-based Dinkelbach--Type method for computing extremal tensor generalized eigenvalues. We show that the extremal tensor generalized eigenvalu…
