Publisher summary· verbatim

arXiv:2501.02373v3 Announce Type: replace Abstract: Task arithmetic in large-scale pre-trained models enables agile adaptation to diverse downstream tasks without extensive retraining. By leveraging task vectors (TVs), users can perform modular updates through simple arithmetic operations like addit
