Robust Domain Adaptation
Robust domain adaptation aims to train machine learning models that generalize well to new, unseen data distributions, overcoming the limitations of traditional models which struggle with data heterogeneity. Current research focuses on improving model robustness through techniques like adversarial training, data augmentation (including adversarial and random transformations), and optimal transport methods to align source and target domain distributions, often within unsupervised or semi-supervised learning frameworks. These advancements are crucial for deploying machine learning models in real-world applications where data scarcity or shifts in distribution are common, particularly in fields like medical imaging and natural language processing.
