NI-GDBA: Non-Intrusive Distributed Backdoor Attack Based on Adaptive Perturbation on Federated Graph Learning

Ken Li, Bin Shi^†, Jiazhe Wei, Bo Dong

WWW2025(Oral).

Project Page / Paper

We propose a non-intrusive graph distributed backdoor attack(NI-GDBA) that does not require backdoor triggers to be injected in the training data.

ALM-PU: Positive and Unlabeled learning with constrained optimization

Jiazhe Wei^*, Yuefei Wu^*, Bin Shi^†, Ken Li, Bo Dong

ECML-PKDD2025(Oral) & Machine Learning

We propose a novel constraint optimization-based PU-learning framework, which overcomes classifiers' negative classification bias and enhances sample discrimination capability by imposing distinct mathematical constraints on labeled and unlabeled sample sets and resolving the problem through systematic optimization.
