Heavy Labels Out! Dataset Distillation with Label Space Lightening (HeLlO) tackles the storage costs associated with large-scale dataset distillation. By leveraging pre-trained foundation models and introducing a novel label-lightening approach, HeLlO achieves comparable performance to state-of-the-art methods while using only 0.003% of the original label storage space. This could make large-scale dataset distillation more feasible for widespread adoption, potentially accelerating AI model training and reducing computational resources.
