Exact Second-Order Asymptotics in Covert Communication Over Discrete Memoryless Channels
Qiaosheng Zhang, Lin Zhou, Xuelong Li
We determine the exact second-order asymptotics of covert communication over binary-input discrete memoryless channels when covertness is measured by variational distance. Previous…
Capacity Region for Covert Secret Key Generation over Multiple Access Channels
Yingxin Zhang, Lin Zhou, Qiaosheng Zhang
We study covert secret key generation over a binary-input two-user multiple access channel with one-way public discussion and derive bounds on the capacity region. Specifically, in…
Community Detection for Contextual-LSBM: Theoretical Limitations of Misclassification Rate and Efficient Algorithms
Dian Jin, Yuqian Zhang, Qiaosheng Zhang
The integration of network information and node attribute information has recently gained significant attention in the community detection literature. In this work, we consider com…
MVPatch: More Vivid Patch for Adversarial Camouflaged Attacks on Object Detectors in the Physical World
Zheng Zhou, Hongbo Zhao, Ju Liu +4
Recent studies have shown that Adversarial Patches (APs) can effectively manipulate object detection models. However, the conspicuous patterns often associated with these patches t…
