Comprehensive Risk Stratification
The MedFusionNet framework is a two-stage approach designed for robust multi-label medical image classification and clinical decision-making. It begins with preprocessing and discretization of continuous variables across multi-modal datasets. The first stage, initial risk classification, employs univariate thresholding and classification trees to identify top-N discriminative features for each label. These selected features are then integrated into MedFusionNet, a multivariate deep learning model, in the second stage for advanced risk stratification. This ensures both interpretability and robust classification performance by leveraging domain-specific metrics and comprehensive label-correlation analysis.
Hybrid Deep Learning Core
MedFusionNet's core is a hybrid parallel deep learning architecture combining Convolutional Neural Networks (CNNs), transformers with Self-Attention Mechanisms, and Feature Pyramid Networks (FPNs). The CNN branch, using Dense Connections, excels in local feature extraction and efficient gradient flow. The transformer branch captures global dependencies and inter-label interactions. FPNs integrate multi-scale features, allowing the model to handle fine-grained details and global context simultaneously. Cross-branch interaction modules facilitate seamless information exchange, enhancing model nonlinearity and representational power across diverse modalities like imaging, text, and metadata.
Superior Diagnostic Performance
Extensive evaluations on two complex multi-modal datasets, NIH ChestX-ray14 and a custom cervical cancer dataset, demonstrate MedFusionNet's consistent superiority. It achieved a 95.35% accuracy on NIH ChestX-ray14 and 92.34% on the cervical cancer dataset, outperforming RestNet50, DenseNet121, ConvNeXt, DeiT, and InceptionResNet. Statistical analysis via Friedman's test confirmed significant performance differences, with MedFusionNet achieving the highest rank sums, highlighting its robust efficacy in challenging medical imaging tasks.
Robustness to Imbalance & Explainable AI
MedFusionNet tackles severe data imbalance in clinical datasets using a multi-pronged approach: class-weighted focal loss, hybrid resampling with balanced mini-batch sampling, feature-level calibration via a class-aware reweighting module, and curriculum-inspired training. This ensures sensitivity to minority, clinically critical conditions. For interpretability, Grad-CAM and LRP are integrated, generating localization heatmaps that highlight discriminative regions in input images. These visual explanations confirm MedFusionNet focuses on pathologically meaningful areas (e.g., lung fields, pleural boundaries), bridging the gap between predictive performance and clinical trustworthiness.
Optimized for Real-world Deployment
Despite its advanced architecture, MedFusionNet is computationally efficient for clinical applications. It converges 40% faster than baselines, requiring fewer epochs for optimal accuracy. While per-epoch cost is higher due to parallel processing, the overall training time to achieve peak performance is competitive. At deployment, MedFusionNet maintains a low inference latency of 52 ms/batch, which is well within clinically acceptable ranges for near-real-time diagnostic support. This balance of performance and efficiency makes it highly suitable for integration into real-world healthcare workflows.

Case Study: Mitigating Data Imbalance in Clinical AI
Clinical imaging datasets frequently suffer from severe class imbalance, where rare but critical conditions are underrepresented. MedFusionNet addresses this with a comprehensive strategy, including a class-weighted focal loss, hybrid resampling (balanced mini-batch sampling), feature-level calibration with a class-aware reweighting module, and curriculum-inspired training. This ensures sensitivity to minority labels, crucial for early detection of critical diseases, and enhances the model's ability to generalize without bias towards common pathologies.
Crucial for early detection of rare diseases and maintaining diagnostic sensitivity.
Case Study: Enhanced Interpretability with Visual Explanations
MedFusionNet incorporates explainability analysis using Gradient-weighted Class Activation Mapping (Grad-CAM) and Layer-wise Relevance Propagation (LRP). These methods generate localization heatmaps that highlight the most discriminative regions in input images contributing to the model's decision. For the NIH ChestX-ray14 dataset, Grad-CAM consistently highlights critical thoracic structures like lung fields, pleural boundaries, and mediastinum for various pathologies. This visual feedback improves transparency and clinical trustworthiness, allowing clinicians to understand why a diagnosis is made.
