Researchers analyze transformer expressivity in language modeling

By PulseAugur Editorial · [1 sources] ·

Researchers have analyzed the probability distributions that autoregressive transformers can express, moving beyond their common treatment as language recognizers. The study reveals that making these models autoregressive can sometimes enhance their expressivity. Furthermore, introducing probabilistic elements can alter equivalences that exist in non-probabilistic transformer models, clarifying the functional capabilities of transformers in their typical role as language generators.

    Probability Distributions Computed by Autoregressive Transformers

    arXiv:2510.27118v4 Announce Type: replace Abstract: Most expressivity results for transformers treat them as language recognizers -- devices that accept or reject strings -- rather than as they are used in practice: as language models that generate strings autoregressively and pr…
