Researchers have developed a new method called Theseus that allows task-specific updates to be transferred between large pre-trained models of different architectures without requiring additional training. This technique focuses on the functional effect of updates on intermediate representations rather than matching parameters directly. Theseus aligns representation spaces using orthogonal Procrustes analysis, enabling a stable, closed-form solution for transferring task identity across models of varying widths, demonstrated successfully in vision and language tasks.
