Conformal Agent Error Attribution

Accepted at NeurIPS 2026 (to appear)

Naihe Feng, Yi Sui, Shiyi Hou, Ga Wu, Jesse C. Cresswell

Naihe Feng and Yi Sui contributed equally.

TL;DR: Uses conformal prediction to identify regions of an agent’s execution trace containing the decisive error, with calibrated coverage under exchangeability, to support debugging and rollback.

Published in ICML 2026

Zhiyuan Su, Naihe Feng, Luther Qin, Ga Wu

Response Quality Assessment for Retrieval-Augmented Generation via Conditional Conformal Factuality

Published in SIGIR 2025

Naihe Feng, Yi Sui, Shiyi Hou, Jesse C. Cresswell, Ga Wu

TL;DR: Combines retrieval signals with conformal prediction to filter claims in RAG-generated answers, providing group-conditional reliability guarantees under the method’s assumptions while retaining useful factual content.
