SMoA: Spectrum Modulation Adapter for Parameter-Efficient Fine-Tuning
Researchers have introduced SMoA, a novel Spectrum Modulation Adapter designed to enhance parameter-efficient fine-tuning (PEFT) for large language models. Unlike traditional methods like Low-Rank Adaptation (LoRA) which face limitations in representational capacity with decreasing rank, SMoA aims to broaden the spectrum of adaptable updates within a smaller parameter budget. By partitioning layers into spectral blocks and applying modulated low-rank branches, SMoA demonstrates improved performance over existing LoRA-style baselines on various tasks. AI
