Adaptive Newton-CG methods with global and local analysis for unconstrained optimization with Hölder continuous Hessian

Ziyang Zeng, Junyu Zhang, Chuan He

In this paper, we study Newton-conjugate gradient (Newton-CG) methods for minimizing a nonconvex function f whose Hessian is (Hf​,I^½)-Hölder continuous with modulus Hf​>0 an…

A New Kernel Regularity Condition for Distributed Mirror Descent: Broader Coverage and Simpler Analysis

Junwen Qiu, Ziyang Zeng, Leilei Mei +1

Existing convergence of distributed optimization methods in non-Euclidean geometries typically rely on kernel assumptions: (i) global Lipschitz smoothness and (ii) bi-convexity of…

Graph-Guided Fused Regularization for Single- and Multi-Task Regression on Spatiotemporal Data

Meixia Lin, Ziyang Zeng, Yangjing Zhang

Spatiotemporal matrix-valued data arise frequently in modern applications, yet performing effective regression analysis remains challenging due to complex, dimension-specific depen…

Multiple Regression for Matrix and Vector Predictors: Models, Theory, Algorithms, and Beyond

Meixia Lin, Ziyang Zeng, Yangjing Zhang

Matrix regression plays an important role in modern data analysis due to its ability to handle complex relationships involving both matrix and vector variables. We propose a class…
