New method merges multi-task AI models without retraining

Researchers have developed a novel training-free method for classifying tasks in multi-task model merging, aiming to improve performance without requiring additional training data or task IDs during inference. The approach, named SiM, utilizes singular value decomposition (SVD)-based low-rank manifold approximations to score tasks based on a test input's projection residual onto each task manifold. This allows for dynamic routing to activate task-relevant parameters, effectively narrowing the performance gap between merged models and individual task experts across various computer vision and natural language processing benchmarks.
