Label-Agnostic Forgetting: A Supervision-Free Unlearning in Deep Models

1 code implementation31 Mar 2024 Shaofei Shen, Chenhao Zhang, Yawen Zhao, Alina Bialkowski, Weitong Chen, Miao Xu

Leveraging this approximation, we adapt the original model to eliminate information from the forgotten data at the representation level.

Machine Unlearning

A Boosting Algorithm for Positive-Unlabeled Learning

no code implementations19 May 2022 Yawen Zhao, Mingzhe Zhang, Chenhao Zhang, Weitong Chen, Nan Ye, Miao Xu

This is because AdaPU learns a weak classifier and its weight using a weighted positive-negative (PN) dataset with some negative data weights $-$ the dataset is derived from the original PU data, and the data weights are determined by the current weighted classifier combination, but some data weights are negative.
