Reliable AI-Assisted Decisions via Selective Auditing

Read the original on arXiv Machine Learning →

The paper introduces a framework for online monitoring of AI systems that produce decisions with associated confidence scores. It formulates the problem as an online constrained optimization task, aiming to minimize expert auditing while ensuring that the proportion of unaudited AI errors remains below a user‑defined threshold. The authors present a family of algorithms with provable error‑control guarantees, including an optimally efficient method that achieves the best possible auditing rate for both adversarial and i.i.d. data streams, and demonstrate its effectiveness on tasks such as screening harmful requests, text annotation, and data labeling.

Adaptive auditing of AI systems with anytime-valid guarantees

The paper introduces a hypothesis testing framework for adaptive auditing of AI systems, addressing the challenge of limited, opportunistically collected data. It defines two competing null hypotheses—one from the model’s perspective and one from the auditor’s—and uses Safe Anytime-Valid Inference (SAVI) to perform betting-based tests that yield simultaneous e-processes. The authors prove that, with a powerful auditor, the two hypotheses become asymptotically inverse, allowing a global robustness certification, and demonstrate empirically that their methods control Type‑I error and can reach conclusions with as few as 20 observations.

PROBE: Learning to Audit Policy Compliance in Tool-Using LLM Agents

PROBE is an algorithm that trains language‑model auditors to probe deployed tool‑using agents for policy violations through realistic, multi‑turn, tool‑mediated dialogue. By framing auditing as a two‑player Markov game and using a composite reward that balances violation discovery, behavioral plausibility, conversation progress, and policy diversity, PROBE outperforms zero‑shot adversaries in uncovering broader and higher‑yield policy violations. The study compares GRPO, DPO, and GFlowNet optimizations, demonstrating that multi‑turn behavioral auditing is a distinct and necessary axis of agent evaluation, complementing existing capability and safety benchmarks.
