New Audit Method Detects Causality Breaks in Sequence Models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new audit method to detect causality breaks in sequence models, which can occur even when attention masks are correctly applied. This lightweight audit, requiring only two forward passes without training or gradients, precisely identifies where representations depend on future inputs. In testing across eight model checkpoints and 192 injected-fault trials, the audit successfully located all defects, including issues in Zamba2 and Nemotron-H, which traditional mask inspection methods failed to detect. AI

IMPACT This new audit method could improve the safety and reliability of sequence models by identifying subtle causality breaks that are missed by current techniques.

    The Mask Is Not the Model: Auditing Prefix Invariance in Attention, State-Space, and Hybrid Sequence Models

    arXiv:2608.22876v1 Announce Type: cross Abstract: We formalize prefix invariance: representations at position t must not depend on future inputs. We give a lightweight audit, two forward passes, no training or gradients, that localizes exactly where causality breaks. Attention-ma…
