Code Monitor Red Teaming for Public-Test-Passing Code
Junchi Liao, Jiawen Deng, Fuji Ren
Visible tests are a common gate for LLM-generated code, but passing them does not certify specification correctness. We study a deployment-like monitoring problem: after code has p…
Auditing Evidence Use in Medical LLM Diagnosis
Junchi Liao, Jiawen Deng, Fuji Ren
Medical LLMs are often evaluated by whether they select the correct diagnosis, but diagnostic accuracy alone does not show whether the model used the case evidence appropriately. W…
Evidence Interfaces Shape How Retrieval-Augmented Readers Use Support
Junchi Liao, Jiawen Deng, Fuji Ren
In multi-hop RAG evaluation, a top-k answer score can hide two different failures: the retrieval window may drop part of the support chain, or it may contain support in a form the…
VISTA: Auditing Semantic Divergence in Vision-Language Models
Junchi Liao, Jiawen Deng, Fuji Ren
Vision-language models can exhibit visual concept-conditioned divergence: given images containing demographic features, corporate logos, or ideological symbols, some models produce…
Modality-Aware Contrastive and Uncertainty-Regularized Emotion Recognition
Yan Zhuang, Minhao Liu, Yanru Zhang +2
Multimodal Emotion Recognition (MER) has attracted growing attention with the rapid advancement of human-computer interaction. However, different modalities exhibit substantial dis…
Beyond Explicit Refusals: Soft-Failure Attacks on Retrieval-Augmented Generation
Wentao Zhang, Yan Zhuang, ZhuHang Zheng +3
Existing jamming attacks on Retrieval-Augmented Generation (RAG) systems typically induce explicit refusals or denial-of-service behaviors, which are conspicuous and easy to detect…
EthicMind: A Risk-Aware Framework for Ethical-Emotional Alignment in Multi-Turn Dialogue
Jiawen Deng, Wei Li, Wentao Zhang +2
Intelligent dialogue systems are increasingly deployed in emotionally and ethically sensitive settings, where failures in either emotional attunement or ethical judgment can cause…
Breakdowns in Conversational AI: Interactional Failures in Emotionally and Ethically Sensitive Contexts
Jiawen Deng, Wentao Zhang, Ziyun Jiao +1
Conversational AI is increasingly deployed in emotionally charged and ethically sensitive interactions. Previous research has primarily concentrated on emotional benchmarks or stat…
TMDC: A Two-Stage Modality Denoising and Complementation Framework for Multimodal Sentiment Analysis with Missing and Noisy Modalities
Yan Zhuang, Minhao Liu, Yanru Zhang +2
Multimodal Sentiment Analysis (MSA) aims to infer human sentiment by integrating information from multiple modalities such as text, audio, and video. In real-world scenarios, howev…
Bridging the User-side Knowledge Gap in Knowledge-aware Recommendations with Large Language Models
Zheng Hu, Zhe Li, Ziyun Jiao +5
In recent years, knowledge graphs have been integrated into recommender systems as item-side auxiliary information, enhancing recommendation accuracy. However, constructing and int…
SSP: A Simple and Safe automatic Prompt engineering method towards realistic image synthesis on LVM
Weijin Cheng, Jianzhi Liu, Jiawen Deng +1
Recently, text-to-image (T2I) synthesis has undergone significant advancements, particularly with the emergence of Large Language Models (LLM) and their enhancement in Large Vision…
Bert4XMR: Cross-Market Recommendation with Bidirectional Encoder Representations from Transformer
Zheng Hu, Satoshi Nakagawa, Shi-Min Cai +1
Real-world multinational e-commerce companies, such as Amazon and eBay, serve in multiple countries and regions. Some markets are data-scarce, while others are data-rich. In recent…
