New Optimal Transport Framework Unifies Cold-Start Active Learning Methods

Researchers have developed a new framework for cold-start active learning, a method for selecting valuable data subsets without prior knowledge. This approach utilizes optimal transport theory to unify existing methods and provides a theoretical analysis of the trade-offs involved. The proposed algorithm, epsilon-Adaptive Selection (epsilon-AS), uses a data-adaptive regularization rule and has demonstrated state-of-the-art performance on various datasets, including ImageNet-1k, where it improved accuracy and reduced selection time.
