Source Domain Subset Sampling for Semi-Supervised Domain Adaptation in Semantic Segmentation [article]

Daehan Kim, Minseok Seo, Jinsun Park, Dong-Geol Choi
2022 arXiv   pre-print
We propose domain adaptation by sampling and exploiting only a meaningful subset from source data for training.  ...  Our key assumption is that the entire source domain data may contain samples that are unhelpful for the adaptation.  ...  Our motivation can be applied in domain adaptation of various tasks other than semantic segmentation. However, pixel-level sampling is dependent on semantic segmentation.  ...
