Multimodal deep learning for biomedical data fusion: a review

Problem

Biomedical data are increasingly multimodal, and researchers lack organized guidance on which deep learning fusion strategies to use.

Why it matters

Choosing fusion strategies well captures complex relationships among biological processes in health data.

What the AI did

Reviewed deep learning data fusion methods and proposed a detailed taxonomy; found deep fusion often outperforms unimodal and shallow approaches, with intermediate joint representation learning preferred.

Results

Qualitative review finding: deep fusion strategies often outperform unimodal and shallow approaches.

Impact

Provides a taxonomy to guide fusion strategy choices in biomedical applications.
