精密診断のためのゲノム臨床統合のための量子変分グラフ駆動ニューラルフレームワーク

Integrating genomic and clinical data for precision diagnosis poses significant challenges due to high dimensionality, non-linear dependencies, and heterogeneity across data types. Existing machine learning and hybrid quantum-classical models often struggle to effectively integrate multimodal biomedical data in a way that is interpretable and scalable. To address these limitations, this research proposes a Quantum Variational Graph-Driven Neural (QVGDN) framework, designed to capture complex cross-modal interactions and relational patient structures with quantum-enhanced computing solutions.

The QVGDN framework incorporates a quantum adaptive interference readout mechanism for modality-specific feature extraction, integrates genomic and clinical features through a variational encoding with cross-factorized attention fusion module, and performs relational diagnosis with a multi-omic quantum entangled kernel-based external graph neural network. The hyperparameters are fine-tuned using the Superb Fairy-wren Optimization Algorithm for convergence efficiency.

The experimental evaluation on two benchmark datasets shows that QVGDN achieves 99.12% accuracy and high performance consistently in noisy and limited data conditions. Compared with classical and hybrid quantum baseline models, QVGDN significantly improves diagnostic precision, sample efficiency, and relational interpretability.

The proposed framework is highly suitable for deployment in clinical decision support systems where interpretability and computational efficiency are essential by offering a scalable solution amenable to real-time precision diagnostics.
