Researchers have developed a new method for low-budget active learning, which focuses on selecting a small, representative subset of data (a coreset) for training models. This approach is particularly useful in fields like medicine where data labeling is expensive. The method utilizes features from a pre-trained self-supervised model and employs entropic optimal transport, specifically the Sinkhorn divergence, as the selection criterion. This technique provides theoretical guarantees on solution quality and allows for efficient computation, outperforming existing heuristics in low-budget scenarios on image and medical datasets. AI
IMPACT This method could reduce the cost of training AI models in data-scarce domains like medicine.
