ARIBA: Towards Accurate and Robust Identification of Backdoor Attacks in Federated Learning

no code implementations9 Feb 2022 Yuxi Mi, Jihong Guan, Shuigeng Zhou

The distributed nature and privacy-preserving characteristics of federated learning make it prone to the threat of poisoning attacks, especially backdoor attacks, where the adversary implants backdoors to misguide the model on certain attacker-chosen sub-tasks.

Learning Competitive and Discriminative Reconstructions for Anomaly Detection

no code implementations17 Mar 2019 Kai Tian, Shuigeng Zhou, Jianping Fan, Jihong Guan

Edit Probability for Scene Text Recognition

no code implementations CVPR 2018 Fan Bai, Zhanzhan Cheng, Yi Niu, ShiLiang Pu, Shuigeng Zhou

The advantage lies in that the training process can focus on the missing, superfluous and unrecognized characters, and thus the impact of the misalignment problem can be alleviated or even overcome.
