FediLoRA: Practical Federated Fine-Tuning of Foundation Models Under Missing-Modality Constraints
FediLoRA addresses two critical challenges in federated Vision-Large Language Models (VLLMs): heterogeneous LoRA ranks and missing modalities. By combining dimension-wise aggregation with a lightweight layer-wise model editing strategy, FediLoRA significantly improves both global and personalized model performance. This approach ensures robustness even with imbalanced computational resources and incomplete multimodal data, demonstrating superior effectiveness in real-world clinical applications.

Federated Learning for Privacy & Collaboration
FediLoRA enhances federated learning by enabling collaborative VLLM training across institutions (e.g., hospitals) without sharing raw data. This preserves privacy while allowing organizations to leverage larger, collective datasets for more robust AI models.
Efficiency through LoRA Fine-Tuning
FediLoRA utilizes Low-Rank Adaptation (LoRA), a Parameter-Efficient Fine-Tuning (PEFT) method. It introduces trainable low-rank matrices for adapting models, significantly reducing computational overhead and making VLLM fine-tuning practical for clients with diverse computing resources.
Addressing Missing Modalities in Multimodal AI
A key innovation of FediLoRA is its ability to handle missing modalities, a common issue in real-world multimodal data (e.g., medical images or text reports being incomplete). It effectively mitigates performance degradation caused by such data incompleteness.

Clinical Application Success: Medical VQA
Challenge: Medical datasets often suffer from high rates of missing modalities and require strict privacy preservation for patient data, making VLLM deployment challenging.
Solution: FediLoRA's federated fine-tuning under missing-modality constraints enables hospitals to collaboratively train robust multimodal VLLMs without sharing sensitive raw data, ensuring privacy and data utility.
Result: Achieved superior accuracy (e.g., 39.2% under 30% missing-modality) compared to baselines on the Medical VQA dataset, ensuring reliable diagnostic models for both small and large medical institutions.
