How Attention Decays: A New Law of Language
![Attention mechanisms demonstrably align with linguistic structure, as evidenced by a correspondence between part-of-speech tags and attention weights - specifically, attention concentrates on nouns and verbs, suggesting the model prioritizes content words during processing [latex] \implies [/latex] a hierarchical understanding of sentence construction.](https://arxiv.org/html/2603.04805v1/2603.04805v1/agf-image/pos.png)
Researchers are finding that the way language models focus on words isn’t random, but follows a predictable pattern reminiscent of gravity.
