EdgePruner: Poisoned Edge Pruning in Graph Contrastive Learning

no code implementations12 Dec 2023 Hiroya Kato, Kento Hasegawa, Seira Hidano, Kazuhide Fukushima

We focus on the fact that the state-of-the-art poisoning attack on GCL tends to mainly add adversarial edges to create poisoned graphs, which means that pruning edges is important to sanitize the graphs.

Magmaw: Modality-Agnostic Adversarial Attacks on Machine Learning-Based Wireless Communication Systems

no code implementations1 Nov 2023 Jung-Woo Chang, Ke Sun, Nasimeh Heydaribeni, Seira Hidano, Xinyu Zhang, Farinaz Koushanfar

Although there have been a number of adversarial attacks on ML-based wireless systems, the existing methods do not provide a comprehensive view including multi-modality of the source data, common physical layer components, and wireless domain constraints.

NetFlick: Adversarial Flickering Attacks on Deep Learning Based Video Compression

no code implementations4 Apr 2023 Jung-Woo Chang, Nojan Sheybani, Shehzeen Samarah Hussain, Mojan Javaheripi, Seira Hidano, Farinaz Koushanfar

Experimental results demonstrate that NetFlick can successfully deteriorate the performance of video compression frameworks in both digital- and physical-settings and can be further extended to attack downstream video classification networks.

RoVISQ: Reduction of Video Service Quality via Adversarial Attacks on Deep Learning-based Video Compression

no code implementations18 Mar 2022 Jung-Woo Chang, Mojan Javaheripi, Seira Hidano, Farinaz Koushanfar

In this paper, we conduct the first systematic study for adversarial attacks on deep learning-based video compression and downstream classification systems.

Degree-Preserving Randomized Response for Graph Neural Networks under Local Differential Privacy

no code implementations21 Feb 2022 Seira Hidano, Takao Murakami

However, this algorithm does not protect edges (friendships) in a social graph, hence cannot protect user privacy in unattributed graphs.

SEPP: Similarity Estimation of Predicted Probabilities for Defending and Detecting Adversarial Text

1 code implementation12 Oct 2021 Hoang-Quoc Nguyen-Son, Seira Hidano, Kazuhide Fukushima, Shinsaku Kiyomoto

In terms of misclassified texts, a classifier handles the texts with both incorrect predictions and adversarial texts, which are generated to fool the classifier, which is called a victim.

TransMIA: Membership Inference Attacks Using Transfer Shadow Training

no code implementations30 Nov 2020 Seira Hidano, Takao Murakami, Yusuke Kawamoto

Transfer learning has been widely studied and gained increasing popularity to improve the accuracy of machine learning models by transferring some knowledge acquired in different training.

Identifying Adversarial Sentences by Analyzing Text Complexity

no code implementations19 Dec 2019 Hoang-Quoc Nguyen-Son, Tran Phuong Thao, Seira Hidano, Shinsaku Kiyomoto

Attackers create adversarial text to deceive both human perception and the current AI systems to perform malicious purposes such as spam product reviews and fake political posts.

Detecting Machine-Translated Text using Back Translation

no code implementations WS 2019 Hoang-Quoc Nguyen-Son, Tran Phuong Thao, Seira Hidano, Shinsaku Kiyomoto

The existing methods detected a machine-translated text only using the text's intrinsic content, but they are unsuitable for classifying the machine-translated and human-written texts with the same meanings.

Detecting Machine-Translated Paragraphs by Matching Similar Words

no code implementations24 Apr 2019 Hoang-Quoc Nguyen-Son, Tran Phuong Thao, Seira Hidano, Shinsaku Kiyomoto

We have developed a method matching similar words throughout the paragraph and estimating the paragraph-level coherence, that can identify machine-translated text.
