Federated Multimodal Architecture with Meta-Learned Trust
DermaGPT leverages a PaLI-Gemma 2 vision-language backbone, fine-tuned with Low-Rank Adaptation (LoRA) for efficiency. It implements a Federated Learning (FL) framework across multiple institutions, enabling decentralized model training without sharing sensitive patient data. To enhance reliability and fairness across heterogeneous clinical sites, a Meta-Learned Trust Function (MLTF) dynamically re-weights client updates based on uncertainty, calibration, and domain-shift indicators, improving robustness and calibration without centralized validation data.
Robust Diagnostic Accuracy and Calibration
The system achieved 90.2% diagnostic accuracy across 11 lesion types and 93.3% accuracy in malignancy prediction. These results were obtained on four institutional datasets and an external cohort of 4,452 biopsy-confirmed images. The model demonstrated well-calibrated outputs under federated training, outperforming local-only baselines and showcasing improved cross-site generalization and reliability, especially on challenging nodes with distribution shifts.
Interpretable, Patient-Friendly Explanations with A-RAG
DermaGPT employs a two-stage pipeline: a vision model for diagnosis, followed by external LLMs (e.g., DeepSeek-V3) for generating interactive, human-readable explanations. An Advanced Retrieval-Augmented Generation (A-RAG) module grounds these explanations in a curated, high-precision dermatology knowledge base, significantly reducing hallucinations and improving factual accuracy and clinical relevance. Expert dermatologists rated these explanations as clear and clinically relevant, augmenting clinician judgment rather than replacing it.
Efficient and Privacy-Aware Edge Deployment
Designed for cost-effective deployment, DermaGPT operates on affordable hardware like NVIDIA T4 GPUs, achieving vision-stage inference latencies of 0.1-0.5 seconds per image. Its lightweight architecture, with ~30 million trainable LoRA parameters and ~37 billion active (MoE) parameters for DeepSeek-V3, makes it feasible for use in resource-limited clinical settings. The federated design ensures patient privacy by keeping raw images local, only transmitting text-based diagnostic summaries when external LLMs are used.

Patient-Centric Diagnosis: Actinic Keratosis
A user uploads an image of a suspicious skin lesion and asks for a diagnosis and treatment advice. DermaGPT processes the image locally, identifies it as Actinic Keratosis (AK), and predicts its malignant potential. An external LLM, augmented by A-RAG, then generates a detailed, patient-friendly explanation, including verified information on AK definition, typical presentation, risk of malignant transformation, and evidence-based treatment options. This workflow demonstrates how DermaGPT provides accurate, interpretable, and privacy-aware diagnostic support, enhancing both patient understanding and clinical decision-making.
