Abstract
A computer-implemented method including: obtaining a pre-trained upstream machine learning model; fine-tuning the pre-trained upstream model for at least two downstream tasks, wherein the fine-tuning comprises: (a) training a target downstream model for a target downstream task, based on a dataset with labeling specific to the target downstream task, and (b) training a nuisance downstream model for a nuisance downstream task, based on a dataset with labeling of characteristics which are specific to the nuisance downstream task and are undesired for the target downstream task; and normalizing the undesired characteristics from the pre-trained upstream model, to prevent biasing of the target downstream model by the undesired characteristics.
