Network-Wide Task Offloading With LEO Satellites: A Computation and Transmission Fusion Approach

no code implementations16 Nov 2022 Jiaqi Cao, Shengli Zhang, Qingxia Chen, Houtian Wang, Mingzhe Wang, Naijin Liu

To address the network-wide offloading problem, we propose a metagraph-based computation and transmission fusion offloading scheme for multi-tier networks.

Low-Interception Waveform: To Prevent the Recognition of Spectrum Waveform Modulation via Adversarial Examples

no code implementations20 Jan 2022 Haidong Xie, Jia Tan, Xiaoying Zhang, Nan Ji, Haihua Liao, Zuguo Yu, Xueshuang Xiang, Naijin Liu

This leads to the problem of a malicious third party using a deep learning model to easily recognize the modulation format of the transmitted waveform.

Mean Field MARL Based Bandwidth Negotiation Method for Massive Devices Spectrum Sharing

no code implementations30 Apr 2021 TianHao Li, Yu Tian, Shuai Yuan, Naijin Liu

In this paper, a novel bandwidth negotiation mechanism is proposed for massive devices wireless spectrum sharing, in which individual device locally negotiates bandwidth usage with neighbor devices and globally optimal spectrum utilization is achieved through distributed decision-making.

Adversarial YOLO: Defense Human Detection Patch Attacks via Detecting Adversarial Patches

no code implementations16 Mar 2021 Nan Ji, YanFei Feng, Haidong Xie, Xueshuang Xiang, Naijin Liu

To improve the ability of Ad-YOLO to detect variety patches, we first use an adversarial training process to develop a patch dataset based on the Inria dataset, which we name Inria-Patch.

Blind Adversarial Training: Balance Accuracy and Robustness

1 code implementation10 Apr 2020 Haidong Xie, Xueshuang Xiang, Naijin Liu, Bin Dong

The main idea of this approach is to use a cutoff-scale strategy to adaptively estimate a nonuniform budget to modify the AEs used in the training, ensuring that the strengths of the AEs are dynamically located in a reasonable range and ultimately improving the overall robustness of the AT model.

Blind Adversarial Pruning: Balance Accuracy, Efficiency and Robustness

1 code implementation10 Apr 2020 Haidong Xie, Lixin Qian, Xueshuang Xiang, Naijin Liu

Furthermore, to better balance the AER, we propose an approach called blind adversarial pruning (BAP), which introduces the idea of blind adversarial training into the gradual pruning process.
