%description
Adaptive and Robust Transfer Learning (ART) is a flexible framework for
transfer learning that integrates information from auxiliary data sources
to improve model performance on primary tasks. It is designed to be robust
against negative transfer by including the non-transfer model in the
candidate pool, ensuring stable performance even when auxiliary datasets
are less informative. See the paper, Wang, Wu, and Ye (2023)
<doi:10.1002/sta4.582>.
