Rubric Judgments Lack Uncertainty: Conformal Weighting for LLM Evaluation

Licheng Pan, Haocheng Yang, Haoxuan Li +7

Rubric-based evaluation is widely used to assess large language model (LLM) outputs by decomposing quality into multiple criteria and assigning each a binary judgment from an LLM v…

Mitigating Cross-Modal Hallucinations by Correcting Modality Misrouting in Omnimodal LLMs

Yu Mi, Licheng Pan, Jiayi Zhu +7

Omnimodal large language models (OLLMs) are susceptible to cross-modal hallucinations under audio-visual interference. We find that, for a substantial fraction of incorrect joint p…
