arXiv:2602.15029v3 Announce Type: replace-cross Abstract: The internal representations learned by language models consistently exhibit striking geometric structure: calendar months organize into a circle, historical years form a smooth one-dimensional manifold, and cities' latitudes and longitudes can be decoded using a linear probe. To explain this neural code, we first show that language statistics exhibit translation symmetry (for example, the frequency with which any two months co-occur in text depends only on the time interval between them). We prove that this symmetry governs these geome
This paper provides a theoretical explanation for the observed geometric structures in AI model representations, moving beyond empirical observation to a foundational understanding of language model behavior.
Understanding the fundamental principles behind how language models organize information can lead to more efficient, robust, and controllable AI systems, impacting their development and application.
The theoretical proof highlights the role of translation symmetry in language statistics, offering a new lens through which to interpret and potentially manipulate AI representations for improved performance.

Increased theoretical understanding of AI language models provides new avenues for research and development.
Improved model interpretability and predictability could accelerate responsible AI deployment and reduce unexpected behaviors.
Deeper insights into learned representations might facilitate novel architectures or training paradigms that require less data or compute for equivalent performance.
