New TTA framework balances multimodal data for improved cancer survival prediction

Researchers have developed a new framework called "Together Then Apart" (TTA) for multimodal survival analysis in cancer prognosis. This approach aims to improve predictions by first aligning representations across different data types, such as histopathology images and genomic profiles, to capture shared signals. Subsequently, TTA emphasizes preserving modality-specific information through an anchor-guided contrastive objective, addressing the limitation of strong cross-modal alignment that can obscure crucial distinct evidence. The framework also incorporates unbalanced optimal transport to handle modality imbalance and noisy correspondences, demonstrating consistent improvements over existing multimodal survival models on TCGA cancer cohorts.
