New survey unifies information theory for multimodal AI learning

A new survey paper published on arXiv proposes a unified information-theoretic framework for understanding multimodal learning. The paper connects concepts like Mutual Information (MI), the Information Bottleneck (IB), and Partial Information Decomposition (PID) to progressively explain how different modalities share, preserve, and complement information. It reviews 170 recent studies and 12 foundational works, organizing multimodal learning around challenges such as cross-modal alignment and information-efficient fusion. The authors introduce the Generalized Multimodal Information Lagrangian as a coordinate system to map existing multimodal paradigms and identify areas for future research, including scalable information estimation and information-aware multimodal learning.
