Researchers have introduced PFAdapter, a novel framework designed to enhance personalized federated learning for Multimodal Large Language Models (MLLMs). This approach hierarchically decomposes LoRA (Low-Rank Adaptation) parameters, separating them into global-shared components for universal multimodal semantics and local-private components for edge-specific adaptation. By employing orthogonality regularization and selective aggregation, PFAdapter significantly reduces communication costs by nearly 50% while improving accuracy by 2.4% to 4.8% across various datasets and tasks.
