SimMMDG — What Should Be Shared Across Modalities?

A short reading note on modality-generalizable representations, shared structure and domain shift.

Question

What does a representation need to capture if we expect it to transfer across both domains and modalities?

Notes

The useful distinction for me is between cross-modal commonality and sensor-dependent evidence. A representation that only compresses common information may become stable, but it can also become weak for tasks that rely on modality-specific cues.

Connection to my work

This is relevant to sensor fusion systems where one modality may degrade or disappear.
