Feedback Interconnected Mean-Field Density Estimation and Control

no code implementations2 Jun 2021 Tongjia Zheng, Qing Han, Hai Lin

Specifically, we propose new density control laws which use the mean-field density and its gradient as feedback, and prove that they are globally input-to-state stable (ISS) with respect to estimation errors.

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.
