Researchers have developed new unsupervised domain adaptation (UDA) frameworks to address the challenge of applying AI models trained on one dataset to different, unlabeled datasets. One approach utilizes dual foundation models, specifically the Segment Anything Model (SAM) and DINOv3, to improve semantic segmentation by enabling learning from a wider range of target pixels and constructing stable, domain-invariant prototypes. Another framework focuses on medical imaging, employing orientation-aware adaptation for brain tumor classification across multi-modal MRI and using RKHS-MMD for robust adaptation in chest X-ray classification, thereby reducing reliance on extensive manual annotations.
