Harnessing Image Question Dependence for Better VLM Test-time Reinforcement Learning

Xinrui He, Ting-Wei Li, Junting Wang +4

Test-time reinforcement learning can adapt vision-language models (VLMs) to unlabeled target data, but its effectiveness is fundamentally limited by the reliability of self-generat…

Does Accuracy Equal Evidence? Reasoning Faithfulness under KV Cache Compression

Mengting Ai, Jingrui He, Yue Guo

KV cache compression is commonly evaluated by final-answer accuracy, implicitly assuming that preserving the answer also preserves the reasoning that supports it. We test this assu…

SafeImpute: Reliable Clinical Data Imputation via Conformal Selection

Xinrui He, Mengting Ai, Junting Wang +2

Clinical care often relies on key laboratory indicators, yet real-world patient visits are sparse and tests are ordered irregularly, leading to pervasive missingness. While many im…
