Generalizing deep neural networks to new target domains is critical to their real-world utility. While labeling data from the target domain, it is desirable to select a subset that is maximally-informative to be cost-effective (called Active Learning). The ADA-CLUE algorithm addresses the problem of Active Learning under a domain shift. The GitHub repo consists of code to train models with the ADA-CLUE algorithm for multiple source and target domain shifts. Pre-trained models are also available.
