On the approximation error for approximating convex bodies using multiobjective optimization

no code implementations11 Mar 2021 Andreas Löhne, Fangyuan Zhao, Lizhen Shao

An MOCP can be solved approximately by Benson type algorithms, which compute outer and inner polyhedral approximations of the problem's upper image.

Latent Dirichlet Allocation Model Training with Differential Privacy

no code implementations9 Oct 2020 Fangyuan Zhao, Xuebin Ren, Shusen Yang, Qing Han, Peng Zhao, Xinyu Yang

To address the privacy issue in LDA, we systematically investigate the privacy protection of the main-stream LDA training algorithm based on Collapsed Gibbs Sampling (CGS) and propose several differentially private LDA algorithms for typical training scenarios.

On Privacy Protection of Latent Dirichlet Allocation Model Training

no code implementations4 Jun 2019 Fangyuan Zhao, Xuebin Ren, Shusen Yang, Xinyu Yang

Latent Dirichlet Allocation (LDA) is a popular topic modeling technique for discovery of hidden semantic architecture of text datasets, and plays a fundamental role in many machine learning applications.
