Secrecy Performance for Finite-Alphabet Inputs Over Fluctuating Two-Ray Channels in FDA Communications

no code implementations11 Jun 2020 Chongjun Ouyang, Sheng Wu, Chunxiao Jiang, Derrick Wing Kwan Ng, Hongwen Yang

To provide system design insights for practical communication systems equipped with the frequency diverse array (FDA), this paper investigates the secrecy performance of FDA systems exploiting finite-alphabet inputs over fluctuating two-ray (FTR) fading channels.

Weakly Supervised Person Re-Identification

no code implementations CVPR 2019 Jingke Meng, Sheng Wu, Wei-Shi Zheng

In the conventional person re-id setting, it is assumed that the labeled images are the person images within the bounding box for each individual; this labeling across multiple nonoverlapping camera views from raw video surveillance is costly and time-consuming.

A Unified Bayesian Inference Framework for Generalized Linear Models

no code implementations29 Dec 2017 Xiangming Meng, Sheng Wu, Jiang Zhu

In this letter, we present a unified Bayesian inference framework for generalized linear models (GLM) which iteratively reduces the GLM problem to a sequence of standard linear model (SLM) problems.

Approximate Message Passing with Nearest Neighbor Sparsity Pattern Learning

no code implementations4 Jan 2016 Xiangming Meng, Sheng Wu, Linling Kuang, Defeng, Huang, Jianhua Lu

We consider the problem of recovering clustered sparse signals with no prior knowledge of the sparsity pattern.
