Partial Domain Adaptation
Partial domain adaptation (PDA) addresses the challenge of adapting machine learning models to target domains where only a subset of the source domain's classes are present. Current research focuses on mitigating negative transfer from irrelevant source classes, often employing adversarial learning, instance weighting, and prototype-based methods to align distributions and improve target classification accuracy. This area is significant because it enables more robust and efficient model deployment in real-world scenarios with incomplete or mismatched data, impacting applications ranging from fault diagnosis to image classification. The development of efficient and robust PDA techniques is crucial for improving the generalizability and reliability of machine learning models in diverse settings.
