Graph is a Substrate Across Data Modalities

arXiv:2601.22384v2 Announce Type: replace Abstract: Graphs provide a natural representation of relational structure that arises across diverse domains. Despite this ubiquity, graph structure is typically learned in a modality- and task-isolated manner, where graph representations are constructed within individual task contexts and discarded thereafter. As a result, structural regularities across modalities and tasks are repeatedly reconstructed rather than accumulated at the level of intermediate graph representations. This motivates a representation-learning question: how should graph structu

Why this matters
Why now

The proliferation of diverse data modalities and the increasing demand for more generalized AI have made the development of unified representation learning crucial.

Why it’s important

This research addresses a fundamental limitation in current AI approaches, where structural regularities are repeatedly relearned, hindering efficient knowledge accumulation.

What changes

The ability to learn and accumulate graph structure across different data modalities will lead to more robust, efficient, and generalizable AI systems.
