Research suggests attention, not a gate, makes latent variables accessible in LLMs

By PulseAugur Editorial · [2 sources] ·

A new research paper explores how language models represent and access latent variables, challenging the idea of a selective "gate" for information admission. Instead, the study suggests that attention mechanisms play a crucial role in gathering these variables within a specific mid-depth window, driven by task demand. The findings indicate that the visibility of a concept increases with task demand, but the presence of the variable itself is not dependent on a gate, and readout measures may not accurately reflect actual usage.

    Gathered, Not Admitted: How Attention Brings a Latent Variable into Verbalizable Form

    arXiv:2608.15022v1 Announce Type: new Abstract: Language models hold latent quantities in a form they can report on, and more of a quantity is present in that form when the task requires reusing it flexibly. What causes a representation to enter that form is open, and the word wo…

    Gathered, Not Admitted: How Attention Brings a Latent Variable into Verbalizable Form

    In language models, flexible reuse demands attention-mediated gathering at a mid-depth window to make latent variables readable, without a selective gate, and readout measures poorly reflect actual use.
