AuditAgent: LLM Agent for Risks Auditing in Recommender Systems

AAAI 2026technical

Auditing recommendation systems has attracted growing attention due to increasing concerns over filter bubbles, unfairness, and data misuse. A common approach is sock-puppet auditing, where autonomous agents interact with platforms to reveal risks. However, existing approaches rely on hard-coded age

Resisting Contextual Interference in RAG via Parametric-Knowledge Reinforcement

ICLR 2026poster

Retrieval-augmented generation (RAG) improves performance on knowledge-intensive tasks but can be derailed by wrong, irrelevant, or conflicting retrieved text, causing models to rely on inaccurate evidence and cascade errors. We propose Knowledgeable-R1, a reinforcement-learning framework that expli…

Indirect Online Preference Optimization via Reinforcement Learning

IJCAI 2025

Human preference alignment (HPA) aims to ensure Large Language Models (LLMs) responding appropriately to meet human moral and ethical requirements. Existing methods, such as RLHF and DPO, rely heavily on high-quality human annotation, which restrict the efficiency of iterative online model refinemen

Jailbreak LLMs through Internal Stance Manipulation

EMNLP 2025

To confront the ever-evolving safety risks of LLMs, automated jailbreak attacks have proven effective for proactively identifying security vulnerabilities at scale. Existing approaches, including GCG and AutoDAN, modify adversarial prompts to induce LLMs to generate responses that strictly follow a

Low-Entropy Watermark Detection via Bayes’ Rule Derived Detector

ACL 2025finding

Text watermarking, which modify tokens to embed watermark, has proven effective in detecting machine-generated texts. Yet its application to low-entropy texts like code and mathematics presents significant challenges. A fair number of tokens in these texts are hardly modifiable without changing the…

PRDetect: Perturbation-Robust LLM-generated Text Detection Based on Syntax Tree

NAACL 2025findings

As LLM-generated text becomes increasingly prevalent on the internet, often containing hallucinations or biases, detecting such content has emerged as a critical area of research.Recent methods have demonstrated impressive performance in detecting text generated entirely by LLMs.However, in real-wor…

Too Consistent to Detect: A Study of Self-Consistent Errors in LLMs

EMNLP 2025

As large language models (LLMs) often generate plausible but incorrect content, error detection has become increasingly critical to ensure truthfulness.However, existing detection methods often overlook a critical problem we term as **self-consistent error**, where LLMs repeatedly generate the same

The Fall of ROME: Understanding the Collapse of LLMs in Model Editing

EMNLP 2024finding

Despite significant progress in model editing methods, their application in real-world scenarios remains challenging as they often cause large language models (LLMs) to collapse. Among them, ROME is particularly concerning, as it could disrupt LLMs with only a single edit. In this paper, we study th…
