RK-core: An Established Methodology for Exploring the Hierarchical Structure within Datasets

1 code implementation10 Oct 2023 Yao Lu, Yutian Huang, Jiaqi Nie, Zuohui Chen, Qi Xuan

Across several benchmark datasets, we find that samples with low coreness values appear less representative of their respective categories, and conversely, those with high coreness values exhibit greater representativeness.

Graph-Based Similarity of Neural Network Representations

1 code implementation22 Nov 2021 Zuohui Chen, Yao Lu, Jinxuan Hu, Wen Yang, Qi Xuan, Zhen Wang, Xiaoniu Yang

Understanding the black-box representations in Deep Neural Networks (DNN) is an essential problem in deep learning.

GGT: Graph-Guided Testing for Adversarial Sample Detection of Deep Neural Network

no code implementations9 Jul 2021 Zuohui Chen, Renxuan Wang, Jingyang Xiang, Yue Yu, Xin Xia, Shouling Ji, Qi Xuan, Xiaoniu Yang

Deep Neural Networks (DNN) are known to be vulnerable to adversarial samples, the detection of which is crucial for the wide application of these DNN models.

Adversarial Sample Detection via Channel Pruning

no code implementations ICML Workshop AML 2021 Zuohui Chen, Renxuan Wang, Yao Lu, Jingyang Xiang, Qi Xuan

Experiments on CIFAR10 and SVHN show that the FLOPs and size of our generated model are only 24. 46\% and 4. 86\% of the original model.

HVAQ: A High-Resolution Vision-Based Air Quality Dataset

1 code implementation18 Feb 2021 Zuohui Chen, Tony Zhang, Zhuangzhi Chen, Yun Xiang, Qi Xuan, Robert P. Dick

The main contribution of this paper is that to the best of our knowledge, it is the first publicly available, high temporal and spatial resolution air quality dataset containing simultaneous point sensor measurements and corresponding images.
