Incremental Pseudo-Labeling for Black-Box Unsupervised Domain Adaptation

no code implementations26 May 2024 Yawen Zou, Chunzhi Gu, Jun Yu, Shangce Gao, Chao Zhang

Black-Box unsupervised domain adaptation (BBUDA) learns knowledge only with the prediction of target data from the source model without access to the source data and source model, which attempts to alleviate concerns about the privacy and security of data.
