A Multi-View Framework for BGP Anomaly Detection via Graph Attention Network

no code implementations23 Dec 2021 Songtao Peng, Jiaqi Nie, Xincheng Shu, Zhongyuan Ruan, Lei Wang, Yunxuan Sheng, Qi Xuan

As the default protocol for exchanging routing reachability information on the Internet, the abnormal behavior in traffic of Border Gateway Protocols (BGP) is closely related to Internet anomaly events.

Epidemic spreading under mutually independent intra- and inter-host pathogen evolution

no code implementations19 Feb 2021 Xiyun Zhang, Zhongyuan Ruan, Muhua Zheng, Jie zhou, Stefano Boccaletti, Baruch Barzel

If, however, the pathogen evolves as it spreads, $R_0$ may change over time, potentially leading to a mutation-driven spread, in which an initially sub-pandemic pathogen undergoes a breakthrough mutation.

Adversarial Attacks to Scale-Free Networks: Testing the Robustness of Physical Criteria

no code implementations4 Feb 2020 Qi Xuan, Yalu Shan, Jinhuan Wang, Zhongyuan Ruan, Guanrong Chen

It is found that both DALR and DILR are more effective than RLR, in the sense that rewiring a smaller number of links can succeed in the same attack.

Subgraph Networks with Application to Structural Feature Space Expansion

no code implementations21 Mar 2019 Qi Xuan, Jinhuan Wang, Minghao Zhao, Junkun Yuan, Chenbo Fu, Zhongyuan Ruan, Guanrong Chen

In other words, the structural features of SGNs can complement that of the original network for better network classification, regardless of the feature extraction method used, such as the handcrafted, network embedding and kernel-based methods.
