Novel Active Learning
Novel active learning methods aim to significantly reduce the cost of labeling data for training machine learning models by strategically selecting the most informative samples for annotation. Current research focuses on addressing the "cold start" problem (poor initial performance with limited labeled data) through techniques like leveraging large language models for sample selection, dynamically adjusting strategies based on model competence, and focusing on data points near decision boundaries or representing minority classes. These advancements are improving model performance across various tasks, including image classification, semantic segmentation, and natural language processing, leading to more efficient and effective machine learning in data-scarce scenarios.
