Based Active Learning
Based active learning aims to improve the efficiency of training machine learning models by strategically selecting the most informative unlabeled data points for annotation. Current research focuses on developing novel query strategies, such as those based on model prediction inconsistencies or uncertainty measures, often employing deep learning architectures. These advancements address limitations of traditional active learning, particularly in open-set scenarios and complex tasks like medical image segmentation, leading to significant reductions in annotation costs and improved model performance with limited labeled data. This has broad implications for various fields requiring large labeled datasets, including healthcare and computer vision.
