ALM-PU: Positive and Unlabeled learning with constrained optimization
Jiazhe Wei*, Yuefei Wu*, Ken Li, Bo Dong, Bin Shi†
Accepted at the proceedings of ECML-PKDD2025 Journal Track as oral presentation.
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.

NI-GDBA: Non-Intrusive Distributed Backdoor Attack Based on Adaptive Perturbation on Federated Graph Learning
Ken Li, Jiazhe Wei, Bo Dong, Bin Shi†
Accepted at the proceedings of WWW2025 Research Track as oral presentation.
We propose a non-intrusive graph distributed backdoor attack(NI-GDBA) that does not require backdoor triggers to be injected in the training data.
