New framework compresses task vectors for scalable AI knowledge transfer

Researchers have introduced Task Vector Bases, a novel framework designed to compress large collections of task vectors used in task arithmetic. This method reduces storage and computational demands by representing task vectors as linear combinations of a smaller set of basis vectors. The framework theoretically guarantees the preservation of addition generalization and enables principled unlearning, with error bounds tied to reconstruction quality. Empirical results demonstrate that the proposed basis construction methods outperform heuristic baselines and can even match the performance of full task vector sets across various applications while offering significant efficiency gains. AI
