A Refined Inertial DC Algorithm for DC Programming

no code implementations30 Apr 2021 Yu You, Yi-Shuai Niu

In this paper we consider the difference-of-convex (DC) programming problems, whose objective function is the difference of two convex functions.

Spatio-Temporal Neural Network for Fitting and Forecasting COVID-19

no code implementations22 Mar 2021 Yi-Shuai Niu, Wentao Ding, Junpeng Hu, Wenxu Xu, Stephane Canu

We established a Spatio-Temporal Neural Network, namely STNN, to forecast the spread of the coronavirus COVID-19 outbreak worldwide in 2020.

A Difference-of-Convex Programming Approach With Parallel Branch-and-Bound For Sentence Compression Via A Hybrid Extractive Model

no code implementations2 Feb 2020 Yi-Shuai Niu, Yu You, Wenxu Xu, Wentao Ding, Junpeng Hu, Songquan Yao

In this paper, we design a hybrid extractive sentence compression model combining a probability language model and a parse tree language model for compressing sentences by guaranteeing the syntax correctness of the compression results.

Discrete Dynamical System Approaches for Boolean Polynomial Optimization

1 code implementation21 Dec 2019 Yi-Shuai Niu, Roland Glowinski

We have tested our ODE approaches and compared with the classical nonlinear optimization solver IPOPT and a quadratic binary formulation approach (QB-G) as well as an exhaustive method using parallel computing techniques.

On Difference-of-SOS and Difference-of-Convex-SOS Decompositions for Polynomials

no code implementations27 Mar 2018 Yi-Shuai Niu

Then, we propose the set of D-SOS and DC-SOS polynomials, and prove that any polynomial can be formulated as D-SOS and DC-SOS.
