arXiv:2606.18627v1 Announce Type: new Abstract: Model merging has emerged as a training-free alternative to multi-task learning, aiming to combine multiple task-specific fine-tuned models into a single multi-task model. Most existing model merging approaches follow the Task Arithmetic paradigm, which decomposes fine-tuned weights into pre-trained parameters and task vectors, and performs merging exclusively in the task-vector space. The effectiveness of this paradigm implicitly relies on the assumption that task-specific knowledge is encoded solely within task vectors. We argue that this assum
This research addresses a fundamental assumption in current model merging techniques, prompted by the increasing need for efficient multi-task AI models as AI systems become more complex and specialized.
Improved model merging techniques reduce computational costs and resource demands for deploying multi-task AI systems, making advanced AI more accessible and efficient for various applications.
The proposed 'PACT' method offers a more effective way to combine specialized AI models, potentially leading to smaller, more capable multi-task models without extensive retraining.
