A Proxy Attack-Free Strategy for Practically Improving the Poisoning Efficiency in Backdoor Attacks

no code implementations14 Jun 2023 Ziqiang Li, Hong Sun, Pengfei Xia, Beihao Xia, Xue Rui, Wei zhang, Qinglang Guo, Zhangjie Fu, Bin Li

To address these concerns, we present a Proxy attack-Free Strategy (PFS) designed to identify efficient poisoning samples based on the similarity between clean samples and their corresponding poisoning samples, as well as the diversity of the poisoning set.

Efficient Backdoor Attacks for Deep Neural Networks in Real-world Scenarios

1 code implementation14 Jun 2023 Ziqiang Li, Hong Sun, Pengfei Xia, Heng Li, Beihao Xia, Yi Wu, Bin Li

However, existing backdoor attack methods make unrealistic assumptions, assuming that all training data comes from a single source and that attackers have full access to the training data.

A scalable approach for developing clinical risk prediction applications in different hospitals

no code implementations21 Jan 2021 Hong Sun, Kristof Depraetere, Laurent Meesseman, Jos De Roo, Martijn Vanbiervliet, Jos De Baerdemaeker, Herman Muys, Vera von Dossow, Nikolai Hulde, Ralph Szymanowsky

We applied the model calibration process at four hospitals, and generated risk prediction models for delirium, sepsis and acute kidney injury (AKI) respectively at each of these hospitals.

Mixed Noise Removal with Pareto Prior

no code implementations27 Aug 2020 Zhou Liu, Lei Yu, Gui-Song Xia, Hong Sun

To address this problem, we exploit the Pareto distribution as the priori of the weighting matrix, based on which an accurate and robust weight estimator is proposed for mixed noise removal.
