Researchers have developed GRINCO, a novel framework for active learning that leverages group-invariant coresets. This method addresses the inefficiency of standard coreset techniques by accounting for data symmetries, such as transformations like rotation. GRINCO operates in a quotient space, treating transformed versions of the same instance as a single entity, thereby optimizing the selection of informative unlabeled samples and reducing labeling costs. Experiments on synthetic and image datasets demonstrate GRINCO's superior label efficiency compared to existing methods, particularly when significant data redundancy exists due to group-induced symmetries.
