New active learning framework tackles imbalanced data with foundation models

Researchers have developed a new active learning framework designed to improve model performance on datasets with imbalanced class distributions and noisy annotations. This approach leverages foundation model priors to make informed decisions between a large foundation model and a smaller model, effectively addressing both label noise and class imbalance across image and text domains. Experiments show this method can achieve over 50% annotation savings compared to existing baselines while maintaining performance and robustness. AI

IMPACT This new active learning approach could significantly reduce annotation costs and improve model accuracy on real-world, imbalanced datasets.
