JevAdvBench

Paper introducing an adversarial benchmark for decision models: one appended opinion flips 12.1% of Jev 1.13 decisions.

Paperresearch

This summary is based on how curated lists describe the project; its README was not available to review.

Overview

JevAdvBench is an arXiv paper presenting what it describes as the first adversarial benchmark for typed decision models. According to the listing, it contains 812 typed questions and 9,744 single-edit attacks against the state those questions are asked about.

The headline finding reported in the listing is that on Jev 1.13, appending a single unverified opinion to the state flips 12.1% of decisions. The authors' recommendation is that the state passed to a decision model should be treated as untrusted input, which matters for any application that feeds user-supplied or retrieved text into Jev. The paper itself was not available for review here, so attack categories and per-type results are not summarised beyond the listing.
