Improving adversarial robustness of deep neural networks by using semantic information

no code implementations18 Aug 2020 Li-Na Wang, Rui Tang, Yawei Yue, Xingshu Chen, Wei Wang, Yi Zhu, Xuemei Zeng

The vulnerability of deep neural networks (DNNs) to adversarial attack, which is an attack that can mislead state-of-the-art classifiers into making an incorrect classification with high confidence by deliberately perturbing the original inputs, raises concerns about the robustness of DNNs to such attacks.

Spec-ResNet: A General Audio Steganalysis scheme based on Deep Residual Network of Spectrogram

1 code implementation21 Jan 2019 Yanzhen Ren, Dengkai Liu, Qiaochu Xiong, Jianming Fu, Li-Na Wang

The proposed scheme has better detection accuracy for three different AAC steganographic schemes and MP3Stego than the state-of-arts steganalysis schemes which are based on traditional hand-crafted or CNN-based feature.

A Procedural Texture Generation Framework Based on Semantic Descriptions

no code implementations13 Apr 2017 Junyu Dong, Li-Na Wang, Jun Liu, Xin Sun

Finally, given a set of semantic descriptions, the diverse properties of the samples in the semantic space can lead the framework to find an appropriate generation model that uses appropriate parameters to produce a desired texture.

An Overview on Data Representation Learning: From Traditional Feature Learning to Recent Deep Learning

no code implementations25 Nov 2016 Guoqiang Zhong, Li-Na Wang, Junyu Dong

Since about 100 years ago, to learn the intrinsic structure of data, many representation learning approaches have been proposed, including both linear ones and nonlinear ones, supervised ones and unsupervised ones.
