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.

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.

Boosting ship detection in SAR images with complementary pretraining techniques

no code implementations15 Mar 2021 Wei Bao, Meiyu Huang, Yaqin Zhang, Yao Xu, Xuejiao Liu, Xueshuang Xiang

In this paper, to resolve the problem of inconsistent imaging perspective between ImageNet and earth observations, we propose an optical ship detector (OSD) pretraining technique, which transfers the characteristics of ships in earth observations to SAR images from a large-scale aerial image dataset.

How Does GAN-based Semi-supervised Learning Work?

no code implementations11 Jul 2020 Xuejiao Liu, Xueshuang Xiang

Furthermore, if the labeled data can traverse all connected subdomains of the data manifold, which is reasonable in semi-supervised classification, we additionally expect the optimal discriminator in GAN-SSL to also be perfect on unlabeled data.

Towards GANs' Approximation Ability

Generative adversarial networks (GANs) have attracted intense interest in the field of generative models.

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.

Stochastic Model Pruning via Weight Dropping Away and Back

no code implementations5 Dec 2018 Haipeng Jia, Xueshuang Xiang, Da Fan, Meiyu Huang, Changhao Sun, Yang He

Addressing these two issues, this paper proposes the Drop Pruning approach, which leverages stochastic optimization in the pruning process by introducing a drop strategy at each pruning step, namely, drop away, which stochastically deletes some unimportant weights, and drop back, which stochastically recovers some pruned weights.
