Graph Representation Learning Augmented Model Manipulation on Federated Fine-Tuning of LLMs

Hanlin Cai, Kai Li, Houtianfu Wang +4

Federated fine-tuning (FFT) has emerged as a privacy-preserving paradigm for collaboratively adapting large language models (LLMs). Built upon federated learning, FFT enables distr…

Nonlinearity as Rank: Generative Low-Rank Adapter with Radial Basis Functions

Yihao Ouyang, Shiwei Li, Haozhao Wang +6

Low-rank adaptation (LoRA) approximates the update of a pretrained weight matrix using the product of two low-rank matrices. However, standard LoRA follows an explicit-rank paradig…
