Robust Completion for Rank-1 Tensors with Noises

Jiawang Nie, Xindong Tang, Jinling Zhou

This paper studies the rank-1 tensor completion problem for cubic tensors when there are noises for observed tensor entries. First, we propose a robust biquadratic optimization mod…

Algebraic Degrees of Generalized Nash Equilibrium Problems

Jiawang Nie, Kristian Ranestad, Xindong Tang

This paper studies the algebraic degree of generalized Nash equilibrium problems (GNEPs) given by polynomials. Their generalized Nash equilibria (GNEs), as well as their KKT or Fri…

Sparse Copositive Polynomial Optimization

Suhan Zhong, Jinling Zhou, Jiawang Nie +1

This paper studies the copositive optimization problem whose objective is a sparse polynomial, with linear constraints over the nonnegative orthant. We propose sparse Moment-SOS re…

Max-Min Bilinear Completely Positive Programs: A Semidefinite Relaxation with Tightness Guarantees

Sarah Yini Gao, Xindong Tang, Yancheng Yuan

Max-min bilinear optimization models, where one agent maximizes and an adversary minimizes a common bilinear objective, serve as canonical saddle-point formulations in optimization…

Log-Polynomial Optimization

Jiyoung Choi, Jiawang Nie, Xindong Tang +1

We study an optimization problem in which the objective is given as a sum of logarithmic-polynomial functions. This formulation is motivated by statistical estimation principles su…

A Tight SDP Relaxation for the Cubic-Quartic Regularization Problem

Jinling Zhou, Xin Liu, Jiawang Nie +1

This paper studies how to compute global minimizers of the cubic-quartic regularization (CQR) problem \[ \min_{s \in \mathbb{R}^n} \quad f_0+g^Ts+\frac{1}{2}s^THs+\fracβ{6}\| s \|^…
