Yejing Huo, Guoheng Huang, Lianglun Cheng, Jianbin He, Xuhang Chen, Xiaochen Yuan, Guo Zhong, Chi-Man Pun·October 24, 2024
Summary
The Incomplete Modality Adaptive Network (IMAN) addresses nasopharyngeal carcinoma mortality prediction with missing modalities. It features Dynamic Cross-Modal Calibration (DCMC), Spatial-Contextual Attention Integration (SCAI), and Context-Aware Feature Acquisition (CAFA) modules. DCMC adapts heterogeneous data, SCAI enhances feature fusion, and CAFA captures multi-scale features. IMAN demonstrates robustness and high predictive accuracy, even with incomplete data, improving treatment outcome predictions and advancing NPC diagnosis and treatment planning.
