A new paper published on arXiv introduces a novel categorical framework for understanding parameter-efficient fine-tuning (PEFT) methods in machine learning. The research proposes viewing PEFT methods as maps from a small parameter space to a larger weight space, allowing for a more abstract comparison of techniques beyond just parameter counts and benchmark scores. The paper introduces invariants like expressivity and training dynamics to analyze these maps and classifies 382 methods based on their formulas, providing formal proofs for all results. AI
