RareLens: Towards End-to-End Rare Disease Care via Aligning Divergent Large Language Model Reasoning

Xi Chen, Hongru Zhou, Shiyu Feng +24

Rare diseases represent one of the most challenging settings for clinical decision-making, where heterogeneous presentations, sparse evidence and limited expertise create persisten…

SaFeR-Steer: Evolving Multi-Turn MLLMs via Synthetic Bootstrapping and Feedback Dynamics

Haolong Hu, Hanyu Li, Tiancheng He +6

MLLMs are increasingly deployed in multi-turn settings, where attackers can escalate unsafe intent through the evolving visual-text history and exploit long-context safety decay. Y…

Large Vision-Language Models Get Lost in Attention

Gongli Xi, Ye Tian, Mengyu Yang +5

Despite the rapid evolution of training paradigms, the decoder backbone of large vision--language models (LVLMs) remains fundamentally rooted in the residual-connection Transformer…

SaFeR-ToolKit: Structured Reasoning via Virtual Tool Calling for Multimodal Safety

Zixuan Xu, Tiancheng He, Huahui Yi +7

Vision-language models remain susceptible to multimodal jailbreaks and over-refusal because safety hinges on both visual evidence and user intent, while many alignment pipelines su…

ClueTracer: Question-to-Vision Clue Tracing for Training-Free Hallucination Suppression in Multimodal Reasoning

Gongli Xi, Kun Wang, Zeming Gao +4

Large multimodal reasoning models solve challenging visual problems via explicit long-chain inference: they gather visual clues from images and decode clues into textual tokens. Ye…

RareAlert: Aligning heterogeneous large language model reasoning for early rare disease risk screening

Xi Chen, Hongru Zhou, Huahui Yi +10

Missed and delayed diagnosis remains a major challenge in rare disease care. At the initial clinical encounters, physicians assess rare disease risk using only limited information…
