Graph attention network-based multimodal approach for lung diseases classification
Lung diseases pose significant diagnostic challenges due to complex symptoms and diverse data sources like chest X-rays and clinical notes. Manual interpretation is time-consuming and prone to misdiagnosis. This research introduces a novel multimodal approach utilizing a Graph Attention Network (GAT) to integrate pre-trained Clinical ModernBERT and RAD-DINO models. By enabling granular cross-modal interactions at the token level, the framework achieves robust multimodal representation learning, significantly advancing lung disease classification. The proposed system demonstrates high accuracy and reliability, outperforming existing state-of-the-art methods and offering an automated alternative to enhance diagnostic precision and clinical workflow efficiency.
This research delivers significant advancements for enterprise AI, particularly in healthcare diagnostics, offering enhanced precision and operational efficiency. The robust performance across diverse data modalities underscores its potential for high-stakes applications.
