FILO framework unifies low-rank adaptation for LLMs, improving efficiency

Researchers have introduced FILO, a novel Fisher-Geometric framework designed to unify and improve low-rank adaptation (LoRA) techniques for large language models. FILO addresses the challenge of singular operators in factor-space updates by providing a method to map preconditioned directions without direct inversion. The framework categorizes existing LoRA optimizers and proposes FILO-Adafactor, which uses the Adafactor preconditioner and a closed-form factor-space solve. This new approach demonstrates competitive or improved performance over existing methods on various benchmarks and models, including GPT-2, Mistral-7B, and Qwen2-7B, while maintaining efficient GPU memory usage.
