Active Domain Adaptation
Active domain adaptation (ADA) aims to improve the performance of machine learning models on a new, related dataset (target domain) by strategically selecting a small subset of target data for annotation and using it to refine a model pre-trained on a different dataset (source domain). Current research focuses on efficient sample selection strategies, often incorporating uncertainty estimation and measures of domain discrepancy to identify the most informative samples, and on developing algorithms that effectively leverage these selected samples to bridge the gap between source and target domains. ADA's significance lies in its potential to reduce the substantial cost and effort associated with data annotation in various applications, particularly in fields like medical image analysis and robotics, where labeled data is scarce and expensive to obtain.
