Objective-Aligned Direct Answer SFT for Robust Multi-Frame Medical VQA

Site Li, Jianyi Hao, Xiaofeng Liu

Multi-frame medical VQA appears to reward increasingly complex adaptation: controller-style inference, localization-aware reranking, static hard-negative mixing, and staged continu…

Inference-Time Agentic Decision Rules Beat Longer Evolving Search for Multi-Image Medical Reasoning

Site Li, Jianyi Hao, Xiaofeng Liu

Multi-image medical VQA is not merely a prompt-length problem; it is a fundamental challenge of agentic decision-making. Medical vision-language agents must aggregate evidence acro…

Embedding Semantic Hierarchy in Discrete Optimal Transport for Risk Minimization

Yubin Ge, Site Li, Xuyang Li +4

The widely-used cross-entropy (CE) loss-based deep networks achieved significant progress w.r.t. the classification accuracy. However, the CE loss can essentially ignore the risk o…
