New Paper Formalizes Sufficiency Gap in Sequence Models

A new research paper introduces a formal mathematical framework to address the "sufficiency gap" in sequence models, particularly concerning their ability to handle unobserved latent states. The paper proposes an external observer mechanism that uses an auxiliary binary signal to improve contextual grounding and tool use. This mechanism can reverse posterior odds induced by textual history when the signal's fidelity surpasses the weight assigned to a misleading regime, though it may not fully close the sufficiency gap without perfect revelation of the latent state.

IMPACT Provides a theoretical framework for improving model interpretability and grounding, potentially leading to more reliable AI systems in high-stakes applications.

    The Need for an External Observer Formalizing the Sufficiency Gap: A Mathematical Extension of Mixture Identifiability and Contextual Grounding in Sequence Models

    arXiv:2605.26711v1 Announce Type: new Abstract: We construct a binary mixed-regime process with one deterministic textual regime and one random regime governed by an unobserved latent state. Even an ideal infinite-capacity sequence predictor that exactly recovers the text-only ma…
