Robust Nearest Neighbors for Source-Free Domain Adaptation under Class Distribution Shift

"The goal of source-free domain adaptation (SFDA) is retraining a model fit on data from a source domain (drawings) to classify data from a target domain (photos) employing only the target samples. In addition to the domain shift, in a realistic scenario, the number of samples per class on source an…
