Classification Accuracy for Dementia (OASIS Paired)
Our Multi-Input Multi-Output (MIMO) network with a learnable Transfer Module (TM) significantly boosted classification accuracy for dementia status assessment on OASIS paired data, demonstrating enhanced modality integration and resilience, critical for clinical deployment.
| Strategy | Accuracy | AUC |
|---|---|---|
| IF-TM (Proposed) | 96.90% | 95.62% |
| Early Fusion (EF) | 85.16% | 78.96% |
| Late Fusion (LF) | 82.48% | 87.37% |
| Prior Work [7] (IF) | 91.34% | 88.24% |
| Prior Work [20] (IF) | 95.00% | 94.00% |
The IF-TM strategy consistently outperforms unimodal baselines and other multimodal fusion techniques by leveraging dynamic feature calibration, ensuring robust performance even with incomplete data. This adaptability is vital for real-world clinical settings where data availability is often inconsistent.

Demographic-aware Model
The implementation of a demographic-aware model (TP4) directly integrates metadata like race and gender, enabling the system to disentangle demographic variability from brain structure and mitigate systemic biases inherent in many AI models.

Enhanced Classification Accuracy (AlexNet, Dataset A)
Integrating a physiologically-aware loss (LPBPK) into our generative model significantly improved breast lesion classification, achieving 93.94% accuracy and promoting biologically plausible synthetic data generation for data-scarce settings in DCE-MRI.
PBPK-DAE-CNN for Physiologically-Aware Data Augmentation
Our novel PBPK DAE-CNN framework explicitly integrates biological characteristics from pharmacokinetic modeling into the data augmentation process for DCE-MRI. This approach generates physiologically consistent synthetic images, enhancing model robustness and generalization.
The architecture couples a PBPK-informed Deforming AutoEncoder with a discriminative classifier, ensuring generated data aligns with tracer kinetics. This innovative pipeline addresses data scarcity by creating diverse, yet clinically plausible, training instances, particularly beneficial for improving classification accuracy in small or unbalanced datasets and achieving greater model resilience.
This method ensures that synthetic data not only expands datasets but also introduces controlled, biologically plausible variability, crucial for training robust and generalizable AI models in medical imaging.
