This paper proposes a novel unlearning framework for GBDT. To the best of our knowledge, this is the first work that considers machine unlearning on GBDT. It is not straightforward to transfer the unlearning methods of DNN to GBDT settings. We formalized the machine unlearning problem and its ...
Extensive experimental results on popular datasets demonstrate that our method achieves superior model utility and forgetfulness compared to the state-of-the-art methods. To the best of our knowledge, this is the first work that investigates machine unlearning in VFL scenarios.Li, Bowen...
[ICLR24 (Spotlight)] "SalUn: Empowering Machine Unlearning via Gradient-based Weight Saliency in Both Image Classification and Generation" by Chongyu Fan*, Jiancheng Liu*, Yihua Zhang, Eric Wong, Dennis Wei, Sijia Liu - OPTML-Group/Unlearn-Saliency
In Federated Learning, where multiple participants and incremental training are involved, existing centralized machine unlearning methods are not directly applicable. In this paper, we propose a federated unlearning method based on projected conflict gradient ascent that removes the impact of class data ...
